Why does Firefox disable the Uninstall button on incompatible and disabled extensions (which should be removed)?

I guess I'm just OCD because I don't want to see a bunch of incompatible and disabled extensions on my list but I can't be the only person who would like to remove them. It seems the obvious choice ... but it is unavailable. Why?

Please don't dodge the question. People have normal adds-ons and extentions that when become incomparable are greyed out and there is no way to uninstall it. Mine is Java at this time. Mine is an extension. I haven't had this enabled since 7 came out apparently I don't need it. So I would like to save space and take the darn thing off the computer. But I can't find a way. Can you please help me? thanks

Just delete that file in the temp folder and cleanup that folder.

Why does Firefox trigger the UAC warning each time I open it?

I design websites and test them across most browsers. We use Windows 7 operating system, and only Firefox triggers the User Account Control message on our test computers, which is a major annoyance when opening instances of Firefox in rapidfire order as web designers do. Is there a way to disable it? The UAC is not triggered by Opera, Safari, Chrome and we have made sure we have not checked properties-compatibility tab - "Run this program as administrator" in both the Firefox.exe file as well as any desktop shortcuts - as advised by several people and contributors to Firefox forums. But that doesn't have an effect. Each time we test, we get the Windows 7 UAC message. We've written to Microsoft several times and they have not replied. We thought perhaps you'd have a solution that actually works.
Thanks

I reinstalled first without deleting everything and then as you suggested. The program now comes up ok when I log in as administrator. However, it is the only program I have that suddenly won't work as a non-administrator without requesting that the administrator approve it to make changes to my computer. I have looked at the permissions and they are the same as for WordPerfect, for example. I don't expect that this program makes changes to my computer that will bother any other users.
Why does Windows 7 think that Firefox is going to change the computer for other users?

Why does firefox ignore the exceptions I entered and disallow pop ups from sites that I have listed to be "allowed"

sometimes the pop up blocker allows the exceptions I have listed but most of the time it does not. Is there any way to fix it so that it always allows the exceptions?

It is possible that you run into this pop-up maximum (the default value is 20).
* http://kb.mozillazine.org/dom.popup_maximum
*http://kb.mozillazine.org/about:config
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do not click the Reset button on the Safe mode start window or otherwise make changes.

Why does Firefox open the printer dialogue box whenever it starts up

When Firefox opens the printer dialogue box automatically opens - why and how do I stop it doing this.
This never used to happen on previous versions of firefox

Some web pages will pop up the print dialog automatically. In particular, pages that websites have specially formatted for printing may do this.
Are you restoring tabs that you previously opened, or starting up with your home page(s)? I suspect that one of them is generating the dialog. You could check by going to each one and reloading the page to see whether it is from that page.

Why does Firefox change the filenames of pdfs when it opens them? They go from normal names to 8-digit random letter/number sequences

When I click to open a PDF from Firefox it behaves very strangely. Instead of opening the PDF with its original filename (say for example: Report_on_the_weather.pdf) it changes the file name on opening. They open up with random 8-digit filenames (for example 5918Bd01.pdf). It does this for all PDF files. I would like to stop this behabviour. Any ideas?
My configuration:
Firefox 4
Windows XP
Adobe Acrobat 8.1 Standard (not the Reader, the full standard application)

cor-el, thanks for responding. As it turns out the machine was compromised, probably due to the Java upgade from 6.x to the supposedly current 7.x version. I suspect one of the 'always open' tabs in my profile was aimed at a site that had been compromised to exploit the java vulnerability that has not apparently been fixed yet.
After removing Java, a current Panda AV scan detected three bad jar files. Further testing with MSCONFIG found a file in startup that did not belong, turns out to be a new exploit with very little coverage on virustotal (neither Panda nor McAfee detected it as malware) but as soon as it was taken out of the startup, Firefox started working perfectly.
Firefox was the parakeet in the cave, tipping over to let me know something was wrong.
The machine is in quarantine until a much more complete analysis is done. We may still rebuild it to be certain.
I'm giving you a 'solved' on this because the windows safe mode boot pointed the way to determining the problem.

Why does Firefox select the last used printer instead of the system default printer on startup?

In the course of using Firefox I selected my color printer to print in color then closed Firefox. When I reopened Firefox later on and sent something to the printer I had assumed it picked up the system default printer, a monochrome laserjet. It picked up the color printer instead. When I restart my other apps they automatically pick up the default printer. Why not Firefox?

Why does Firefox (after the latest update) open an additional tab "What's new"? It causes my laptop to crash, including my "Session restore"

Mozilla Fireox Session Restore fully functioned. However, not after latest update (10.0.2). It takes a lot time to load the (additional tab) page "what's new?" / "Firefox add-ons" after which the script running Session Restore fails.
Only occurs after (re)starting laptop.
How do I remove this addional tab ?
It's irritating.

Hi Murdock_1,
You should look at [https://support.mozilla.com/kb/Firefox+has+just+updated+tab+shows+each+time+you+start+Firefox this article about that specific issue] and the article [http://kb.mozillazine.org/Preferences_not_saved Preferences not saved]. These should give you all the information you need!
If that doesn't work:
# Type about:config in the address bar
# Click ''I'll be careful, I promise'' if prompted
# In the Filter input field type ''startup''
# Double click on startup.homepage_override_url
# Delete the text string and click ''OK''
# Close Firefox and reopen the window to verify that it has worked.
Hopefully this helps!

Why does Firefox 4 not open video files (news and youtube) at all, but Firefox 3 and MSIE 8 open these video files quickly, all on my Dell Dimension 8250 desktop with MS Windows XL Pro?

I subscribe to an Earthlink package of telephone and ISP through DSL in Dallas, Texas. To avoid the congestion (time outs and files not found) of the virtual "cloud" servers, as a workaround I connect to the Internet through dial-up on each session on my pc. There is only one pc or computer on my local network. I downloaded Firefox 4 RC and it failed (would not open video files on the Internet), so I removed the Firefox 4 RC program from my pc, and then I downloaded and installed Firefox 3.6.16, which works fine.
My operating system is Windows XP Pro.

Try disabling hardware acceleration. Many visual bugs can be attributed to issues with graphics drivers.
(Firefox -> Options -> Advanced -> General -> [ ] Use hardware acceleration when available)

Why does firefox 3.6.15 close so slowly and erratically?

'''bold text'''When I close down the web browser after viewing any web site, the window closes very slowly and erratically.

Well, this may not help anyone else, but I figured out my issue.
After reinstalling 3.6.4, it too was doing the same thing, using 25% CPU consistently, unable to move the window around, etc.
As bizarre as it sounds, this seems to have been an issue with having a tab open playing flash video during an update/install.
After 3.6.4 was doing it as well, I closed the justin.tv tab and restarted 3.6.4, opened justin.tv back up and it was fine using 2-4% CPU or so instead of 25%. Window can be moved around again too.
Downloaded the full 3.6.6 installer, closed the jtv tab, reinstalled 3.6.6, launched, and reopened a tab for jtv... fine still using 2-4% CPU tops.
Very bizarre. Nothing else changed during any of this other than whether I had JTV open and playing video during the update/install and subsequently if it would be loading as soon as it restarted after the update/install.
After the initial startup, I can close and reopen Firefox as much as I want with the JTV tab open and playing and it has no further issues.
Weird.

Why does Firefox remember the pages I've visited, even though I am using different computers? I've never used the sync function. I don't want my computer at work to be synched with my personal computer at home

My computer at work remembers the pages I've visited even though I visited the pages while I was using my computer at my home. I don't know how or why this is happening, and I don't like that it is in sync with my computer at home - I have never used that function.
For example - When I type in "the methodist hospital" into the search bar using the computer at home, all the search results come up from Google, so I click on the links and take a look around on the websites/pages. The next day, I walk into work, and I type in "the methodist hospital" again in the search bar, and when the results come up - it indicates in gray lettering that "[I] visited this page [yesterday's date]."
Please explain why this is happening and what I must do in order for it to stop. It is scary knowing that my browsing history is remembered using 2 completely different computers. Needless to say, I don't want my boss thinking I'm just surfing the web all day at work.
Thanks in advance!

if i have to read any comment by matt n again i will throw up...in my mouth. i have gone all over google trying to figure out what the f ff did to me without my permission, i have updates turned off so there should be no prompting to restart, there should be a polite offer not a forced update. i am angry and so are a ton of people.
everytime i go to a new complaint, another angry fellow ff user there is matt n with his infuriating smiling little picture...telling me about the awesome safety and security of the new ff...ignoring that a supposed safe but ugly and unusable browser is worse than a customized, beautiful, well functioning browser...with supposed safety issues. i am so angry i cannot express how this has wasted my time. i have been online for 2 hours now figuring out how to fix, apparently i cannot. my old theme is not compatible now...so i am screwed.
good bye. if i wanted chrome i would have had chrome. but i have no choice now.

Why does Firefox display the "Web Gemini" Front page incorrectly?

When the "Web Gemini" front page loads the GAL Logo is in the wrong place.

Reset the page zoom on pages that cause problems: <b>View > Zoom > Reset</b> (Ctrl+0 (zero); Cmd+0 on Mac)
* http://kb.mozillazine.org/Zoom_text_of_web_pages
If you have increased the minimum font size then try the default setting 'none' as a high value can cause issues like you described.

Why does firefox say this not a trusted site and that legitimate businesses are trusted by Firefox

Hi,
One of my partners in New York just sent me an email to say that when he went onto our site www.101BusinessInsights.info a huge banner appeared on his screen saying " this not a trusted site and that legitimate businesses are trusted by Firefox"
Please can you advise why this is so and what can be done to make sure this does not happen.

Why does Premiere render the same sequence sometimes fast and sometimes really slow?

I use Premiere Pro CC 2014.
I have a Nvidia GTX 590
Intel Core i7 X990 @ 3.47GHz
24GB RAM
Windows 7 (64)
200GB free space on an SSD drive and 2 more drives with each 1TB free.
I'm having trouble with performance when rendering sequences.
The sequences themselves are pretty simple. They contain MOV files from my Canon EOS 5D Mark III and transparent PNG files as overlays for titles and additional graphics.
I also use lumetri looks and have turned on Cuda rendering. As a codec for exporting I use H264 (fullhd, 25fps, 20mbits, 2pass, max render quality, max depth)
Whether or not I export in Premiere or via AME doesn't matter, the problem stays the same.
Now, when I start exporting, at one point, which is seemingly random (sometimes at 35%, sometimes at 60%, sometimes at 2% - I'm talking about the same sequence!) rendering becomes really really slow (~1 hour for a 3min video), and I don't understand why. I keeps slow until the whole sequence is finished. But before that, rendering was fast!
But sometimes, I'm lucky, and - after restarting my computer and Premiere, the same sequences render in whole, in under 2 minutes!
So obviously my computer is able to render fast. But it does not always do that. Sometimes - even after a fresh reboot, I'm out of luck and the same sequence renders in an hour - but only after a random point in the sequence.
It's as if Premiere stumbles and can't get up again. The only thing that CAN help (though does not alway), is rebooting the system and hoping for the best.
Where does this strange behaviour come from? I use ordinary footage, ordinary filters and an ordinary export codec. I have lots of RAM and lots of disk space
I have not found a topic in this forum with a similar problem

Similar problem here but on a Mac. AME is always much slower than directly exporting from Premiere, but if I start to get slow renders a reboot always sorts the issue out.
