After every Firefox 34.0 reloading my add-ons have been switched off by unknown program or virus.

After every Firefox 34.0 reloading my add-ons have been switched off by unknown program or virus. Although i can switch them on and reboot firefox one more time to fix it, but it is a little bit boring. How can i solve this problem?

  • I have been using firefox aurora 7 for mac. Most of my handful of add-ons have been disabled -- including Read It Later and Feedly, which I was making good use of. Can you tell me when they will be enabled for firefox aurora 7?

    I have been using firefox aurora 7 for mac. Most of my handful of add-ons have been disabled -- including Read It Later and Feedly, which I was making good use of. Can you tell me when they will be enabled for firefox aurora 7? Maybe I should go back to firefox 6

    You can use the Tab key to select a search engine on the bottom bar and press Enter to use the search engine to do the search.
    *https://support.mozilla.org/kb/Search+bar
    In the current Firefox 34 release there is a new "one-off" search bar.
    This search bar doesn't show the name of the search engine and a logo.
    You can type one letter to make a drop-down list appear where you can see suggestions and see the used search engine and that also has bar at the bottom where you can select other search engines that are enabled via the Search tab in Options/Preferences.
    You can use the Tab key to select one of the other available search engines and press the Enter key to search with the selected search engine.
    Click the search engine icon and click "Change Search Settings" to open the Search tab in Options/Preferences (positioned between Tabs and Content) to select the default search engine and select which search engines to show in the search bar drop-down list that opens when you start typing search terms.

  • How do I know which add-ons have been validated as safe? When clicking "Add to Firefox" I get the scary warning window about only using add-ons from trusted

    The scary warning that appears when I click "Add to Firefox" for a certain add-on discourages me from actually installing it.
    "Install add-ons only from authors whom you trust. Malicious software can damage your computer or violate your privacy . . . (author not verified)"
    In particular, I'm interested in the Password Exporter add-on. I want to be especially cautious as this will access all my passwords stored in Firefox. How do I actually know if an add-on is safe or not?

    If you are talking about "Password Exporter 1.2.1", it's safe as I have been using that add-on for years and love it.

  • How do you uninstall Firefox 5.0? seven of my add-ons have been disabled

    Just upgraded to 5.0 and too many of my add-ons are not compatible. How can I get back to 4.0?

    If an extension worked in Firefox 4.0, it should be working in Firefox 5.0 as well -- [http://blog.mozilla.com/addons/2011/05/21/firefox-5-compatibility-bump/ Firefox 5 Compatibility Bump]
    You can force 5.0 "compatibility" with the "[https://addons.mozilla.org/firefox/addon/add-on-compatibility-reporter/ Compatibility Reporter]" extension, or with [http://kb.mozillazine.org/Extensions.checkCompatibility extensions.checkCompatibility] using about:addons.
    When you reinstall a different version, at the end of the install, don't let the install start Firefox for you, rather exit, and then start Firefox in the normal manner to avoid inadvertently creating and using a new profile without your bookmarks, etc.
    If you think your only alternative is going back to 4.0 or 4.0.1 you can get it at Firefox [ftp://ftp.mozilla.org/pub/firefox/releases/ releases] (all releases, including 4.0.1 and 5.0).

  • Every night at 7pm CST/midnight GMT, Firefox closes with no error message, or warning message. All add-ons have been disabled. Running Win7 with Firefox.

    I have already disabled all ad-ons, one at a time (11 total) to see if any of them caused the error. None did. I have already checked all programs, including antivirus to see there was a timed action that was triggering the shut down. When it does shut down, I receive no error messages or warnings about muliti-tab shutdown. Every time, Firefox simply closes. When I re-open Firefox, I do not receive the option (which I have set) to restore my tabs. No other programs are affected. I am happy to provide any more information, just let me know what you need. The Troubleshooter data below is from 1.5 hours after the most recent Firefox shutdown.

    I have '''exactly''' the same problem as you do, and it also happens in other browsers as well (I use Internet Explorer and Google Chrome too).
    Most of the times, the restore previous session option is grayed out, but other times it automatically asks me if I want to restore the previous session. When I click 'Yes', it restores all the tabs of the previous session alongside a new one, open in the following site: http://krzemik.pl/
    The site is Polish, but I don't even live in Poland.
    The site says it's safe, but I'm suspicious it distributes some kind of adware that causes this problem. I've already reported it, though.
    I also have another problem that, whenever I search for something that contains the word 'virus' on a search engine, the browser is automatically shut within 1 or 2 seconds without any kind of warning or error message, I also can't open one of my antispyware programs (AdAware, to be exact), as it is immediately closed as if I had clicked the 'X', per say, even in Safe Mode. I'm also prevented from using my backup restore function in the control panel, or even using commands to activate it. I've fully scanned my computer in Safe Mode using another antispyware (SuperAntispyware) twice, and nothing as solved the problem.
    I'm not sure if these problems are interconnected, though.

  • Third-party cookies: Should I be concerned that I am forced to accept in order to access a site, if I delete them after every Firefox session?

    Friday 16 August, 2012
    My internet service provider (https://my.gci.net/) blocks my entry to eMailGuard (a GCI spam and virus isolator) when I have third-party cookies disabled
    When I allow third-party cookies I am able to access eMailGuard. I have used GCI eMailGuard and Firefox together for years and have had no such difficulty in the past.
    This problem commenced 2-3 weeks ago.
    I have followed all directions at http://support.mozilla.org/en-US/kb/websites-say-cookies-are-blocked-unblock-them to clear all cookies and cache, with no change. Also, my default setting (see below) is to “Clear history when Firefox closes.” If I understand correctly, clearing history will also clear cookies and cache, so I do it every time I close Firefox.
    Has Firefox changed third-party cookies parameters recently? GCI of course claims this is a browser issue. Should I be concerned about third-party cookies if I delete them after every Firefox session? Any comments or thoughts are greatly appreciated.
    My current version is Firefox v.14.0.1
    My Privacy settings are:
    • Tools\Options\Privacy
    • Use custom settings for history
    My selected (checked) custom settings are as follows:
    • Remember my browsing history
    • Remember download history
    • Remember search and form history
    • Accept cookies from sites (third-party cookies not selected)
    • Keep until: I close Firefox
    • Clear history when Firefox closes
    Thanks,
    James Lavery

    ''Keep until: I close Firefox''
    That's what I use for all cookies. If you start a new session every time you start Firefox, i.e., you don't resume the same session over and over, websites cannot track you 'across sessions' using cookies; you are a new person to them during each session (unless/until you log in).
    Note that "Flash cookies" need to be managed separately.
    As for this particular site, if you want to spend some time research it, you could install an add-on such as Firebug or the external Fiddler2 proxy. Both will show you each request made by the browser when you load a page. Then you can see which third party sites are involved and if you like make a specific entry to allow them in the Exceptions dialog.

  • Firefox crashes when opening "Extras Add-ons"

    Firefox crashes when opening "Extras>Add-ons" (German user interface - I don't know what the according menu points are labeled in English).
    The crash seems to be so severe that no crash ID is created. On every restart after a crash Firefox 4 is in offline mode and has to be switched back to online mode. If needed I could provide a screenshot of the error message shown when firefox crashes.
    There were no problems on this machine running firefox 3.xx. The problems occurred after upgrading from firefox 3.6x to firefox 4.

    Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).<br />
    See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]<br />
    <br />
    If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.<br />
    You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.<br />
    You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

  • Why does my itunes crash after start up with an "APPCRASH" error every time i open it?! I have been trying to fix this for weeks but all i can do it re-install it every other day which does nothing!

    Why does my itunes crash after start up with an "APPCRASH" error every time i open it?! I have been trying to fix this for weeks but all i can do it re-install it every other day which does nothing! I am desperate to get access to my itunes to get music on my phone and all of this just makes me want me to sell my iphone since there is no other way to add music to my phone. If things go get sorted soon you can say goodbye to my support.

    For general advice see Troubleshooting issues with iTunes for Windows updates.
    The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
    The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for installation or performance issues, or compatibility with QuickTime or third party software.
    Your library should be unaffected by these steps but there are also links to backup and recovery advice should it be needed.

  • Firefox 14.0.1 Get Add-ons stuck on "Loading"

    I just purchased a new computer and, in utter spite of Internet Explorer, have downloaded trusty ol' Firefox. Unfortunately, the Get Add-ons is stuck with a bubble that says "Loading" but never actually does.
    I am using Firefox version 14.0.1, downloaded directly from the Mozilla site. I have let the thing load for almost an hour, and nothing has happened. I have tried clicking on "Extensions" or "Appearance", etc. but it hasn't helped. Every time I go back to the Get Add-ons tab it will simply say "Loading." I have also tried doing a search for a specific add-on, only to get the same thing, but in the "Search" tab.
    I have also tried rebooting the computer, rebooting Firefox, and uninstalling and reinstalling Firefox (i kept my preferences, etc. when I did this).
    Does anyone have any suggestions? I really love Firefox and I hate to think that I would have to find another browser to use because I can't download Adblocker Plus.

    Only had to remove the extensions.sqlite, and it fixed the problem perfectly. Thank you very much.

  • I have just updated to 10.7.3 and safari always reloads previous pages I have been on every time on open it, my home page is set to google yet it always reloads from the history, how do I stop this

    I have just updated to 10.7.3 and safari always reloads previous pages I have been on every time on open it, my home page is set to google yet it always reloads from the history, how do I stop this

    There is a setting in the System Preferences for this as well that may be causing it. Go to System Preferences>General>Restore windows when quitting and reopening apps - at the bottom of the window under Number of Recent items. Remove the checkmark from that setting.
    Also - if you close all of your windows when you are done with Safari - it should open to your home page.

  • Since installing Firefox 4 Beta 5, the Add-Ons manager is empty. My add-ons still appear to be installed and working, but I can't install more, or uninstall, or configure them.

    My add-ons still appear to be installed and working, but I can't install more, or uninstall, or configure them.

    Try forcing Firefox to rebuild the list of installed add-ons.
    # Open the profile folder, for details of how to access it see the [[profiles]] article.
    # Close Firefox, then delete extensions.sqlite (you can also delete extensions.cache, extensions.ini, extensions.rdf if they exist)
    When you restart Firefox the list of installed add-ons should be rebuilt.
    If that did not work, you may have an add-on that is causing the problem, try the options in the [[troubleshooting extensions and themes]] article.
    If you type '''about:addons''' into the location bar does that bring up the list of add-ons? I have seen a blank add-ons list if Mr Tech Toolkit add-on is installed, accessing the add-ons manager by typing about:addons in the location bar is a workaround with that add-on installed. The author of that add-on is working on an update.

  • Every previous episode on all my podcasts has now been switched to "unplayed" in 11.2, so instead of a dozen unplayed episodes, i now have 2000. WHY?

    Every previous episode on all my podcasts has now been switched to "unplayed" after updating to 11.2, so instead of a dozen unplayed episodes, I now have 2000. WHY? and I can NOT select and mark them and "Played" if they aren't downloaded.

    Thanks for the replies. It took a while not hearing anything so thought I was alone. I have done many of the suggestions already. The key here is that it occurs on both phones with apps, and phones still packaged in a box.
    A Genius Bar supervisor also checked his Verizon data usage log and found the same 6 hour incremental use. Suprisingly, he did not express much intrigue over that. Maybe he did, but did not show it.
    I think the 6 hour incremental usage is the main issue here. I spoke with Verizon (again) and they confirmed that all they do is log exactly when the phone connected to the tower and used data. The time it records is when the usage started. I also found out that the time recorded is GMT.
    What is using data, unsolicited, every 6 hours?
    Why does it change?
    Why does it only happen on the iPhone 5 series and not the 4?
    Since no one from Apple seems to be chiming in on this, and I have not received the promised calls from Apple tech support that the Genius Bar staff said I was suppose to receive, it is starting to feel like something is being swept under the rug.
    I woke up the other day with another thought ... What application would use such large amounts of data? Well ... music, video, sound and pictures of course. Well ... what would someone set automatically that is of any use to them? hmmm ... video, pictures, sound. Is the iPhone 5 succeptible to snooping? Can an app be buried in the IOS that automatically turns on video and sound recording, and send it somewhere ... every 6 hours? Chilling. I noted that the smallest data usage is during the night when nothing is going on, then it peaks during the day. The Genius Bar tech and I looked at each other when I drew this sine wave graph on the log print outs during an appointment ...

  • My add-ons have disapeared and the layout of mozilla is different since the last update to 4.0.1, why?

    The following add-ons have totally disapeared from my mozilla, but are still working since they are popping up. they are: WebMail Notifier, FoxClocks, Download Statusbar Mini along with some others. Not only did this happen, but the whole Mozilla Firefax layout has been scrambled ever since the last update has been applied.

    To make v4.0.1 look like the previous version, do the following.
    * Right click a blank part of the tab bar and click "Tabs on top" to remove the checkmark. Tabs will subsequently reappear below the location bar.
    * Repeat the same steps, but click the top one called "Menu bar". This will reinstate the text links at the top.
    * To rearrange the layout, repeat the same steps but choose "Customize" from the menu. A panel will open and while that remains onscreen, you can move elements like toolbars, buttons etc around and place them anywhere you wish. You can also drag anything you don't like into that panel and add anything you want by dragging it out of there.
    * To replace the status bar at the foot of the page, install this add-on: https://addons.mozilla.org/en-US/firefox/addon/status-4-evar/
