How do I return to a previous version of firefox?

Occasionally, when there is a firefox update, it resizes my browser page so that the text is tiny. Sure I can hit ctrl and scroll up, but this just resizes the current page I'm on. This has happened to me once before, and I had to reload a previous version of firefox.

You can increase the String pref layout.css.devPixelsPerPx from 1.0 to 2.0 in 0.1 steps to see what works best.
In Firefox 3.6 and later this pref is a String value parsed to a float and allows to fine tune the dimensions of all elements more precisely.
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website. 
If you see a warning then you can confirm that you want to access that page.

How can I return to a previous version of firefox?

At this moment I'm running Firefox 35.0.1, and I think I wish to return to whatever was the previous version. I think Firefox updated to this version several weeks ago, and since then strange things are happening.
First of all, I don not like the "manage search engine" set-up. It's different than the one I had a few weeks ago. Now there's nothing at all wrong with this new incarnation, I just don't like the drop down box, etc, (very small issue).
My real concern is, when I'm on a web page, (pick one), any web page, I'll begin hearing audio from some ad. I frantically search the page to see where I can stop the audio, never finding any option. I'll minimize my window, to see if something is behind that window, which I can shut off, but to no avail. This has happened 3 times in the last 48 hours.
Not earth shattering issues, I realize.
But the question would be, is there an easy way that one could return to the version prior to 35.0.1, without damaging anything, (I'm not extremely tech savy).
Thanks in advance, etc.
greg

Changing versions often does not cure problems, but it does increase risks.

The search options will not be changed by downgrading, but there is a method of changing that without downgrading.

I am not sure the changes in Firefox 35.0.1 would cause your audio issues
* https://www.mozilla.org/en-US/firefox/35.0.1/releasenotes/
The first step in troubleshooting that may be to identify the tab or page involved, then try Firefox with only the newtab page and the problem page open.
IIRC Firefox is intended to continue streaming audio even if a tab does not have focus. That enables users to stream audio in the background whilst browsing. What you hear may be intended behaviour.

Since updating to Firefox 4.0.1 I have lost the site security ranking provided by Norton. can I incorporate this in the latest Firefox? Failing that, how can I return to my previous version?

How to return to a previous version of Firefox?

I didn't like the most recent update to Firefox, nor did I like the one before that. Is there any way to return to a previous version of Firefox? If not, then I'm off to check out Google Chrome via my Safari browser. I don't want to use Firefox in the newer versions at all.

Never mind, I figured it out!

I downloaded the newest version of firefox today 8/16/11 and now I cannot use Evernote (nor does clipmarks work from before) this is unacceptable. How do I return to the earlier version of firefox? Thank You, Carol Roberts

I downloaded the newest version of firefox today 8/16/11 and now I cannot use Evernote (nor does clipmarks work from before) this is unacceptable. How do I return to the earlier version of firefox? If there is no way to do this, then I will have to use internet explorer so I hope you can help me with this. Thank You, Carol Roberts

Until Evernote updates their add-on to mark it compatible with Firefox 6, you can use the [https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/ Add-on Compatibility Reporter] to try re-enabling it yourself.
You can also downgrade to a previous version of Firefox from [https://ftp.mozilla.org/pub/mozilla.org/firefox/releases/ this archive], but please be warned that some old versions of Firefox have known security bugs that are fixed in later versions.

Many thanks b Noir
This is a copy of ONEof the keys in the registry I changed as told by Apple support today. I also have changed others as instructed by GEAR software support to manually delete GEAR drivers (that I had installed but couldn't delete some of the others they mentioned from Windows system 32. Then some bright spark at work told me I need the Gear drivers so I downloaded the software and installed again.
Sorry, just this minute went to insert image and it is giving me a message saying this sort of content is not allowed?.
The most recent key I altered is in: HKey _local _machine. System\class - 4D36E965-E325-11CEBFC1-08002BE10318. Upper Filter data: Upper filter NTIDrvr SiRem GEARAspiWDN.

How can I return to the previous version?

''locking this thread which was started back in February about Firefox 26 / 27''
Yesterday, while trying to get rid of the uninvited AVG elements in my Mozilla opening page I some how installed the latest version of Mozilla which I really dislike. Given this is on my wife's computer while she is away and she does not like changes to her computer I would really appreciate it being returned to the previous version.
I also consider your instructions on how to do anything regarding setting up Mozilla as absolutely terribly written.

Your current level 29 is TERRIBLE on my iMac and I want to go back a level, until you fix it!!!! Help?????!!!!!

How do you downgrade to a previous version of firefox?

How do you down grade to a previous version of Firefox on an Android Phone? Current versions of Firefox no longer work with our WIFI network. Starting sometime around version 33 or 34 we started noticing that while using WIFI, Firefox would freeze every minute or two. Basically it would start to load a page then the progress bar would stop about 1/6th of the way across the screen. If you wait several minutes the bar would continue to about 5/6th of the way across the screen and then stop and not continue to load the page. If you turn WIFI off and then back on, Firefox will again work for a minute or two then freeze again. The timing is very specific and is not bound by a number of clicks. It also happens on all websites. The problem is not with the WIFI network because all programs including Chrome and the Android Browser work fine with WIFI. Also previous versions of Firefox work fine with the WIFI. We have the problem across several phone and manufacture types as well as across Android versions. We also did not have the freezing problem during a time of lower WIFI usage. So the problem specifically has to do with using newer versions of Firefox on a busy WIFI network. Because it may take time to fix these issues in Firefox we would like to downgrade to a previous version of Firefox that we know works with our WIFI network.
Thanks for your help!

Hi Roland
Here are the answers to your questions:
What models of Android tablets and phones are you using?
Samsung Note 4 (running Android 5.0.1), Samsung Rugby Pro (Running Android 4.1.2), Galaxy S5 Active (running Android 4.4.4) & Kyocera-E6560 (Running Android 4.4.2). There are others, but these are the ones I have access to right now.
What version of Firefox for Android are you using?
I started noticing the problem with version 34 on. It could have started with earlier versions but I first noticed it with version 34--we did a large phone upgrade and installed version 34 which was the current version at the time. I just tried 37.02 and am still having the problem.
As a side note I have an old Samsung note 1 (on Android 3.0.8). It is running Version 17 of Firefox and does not have the same problem.
Steps to reproduce: What did you do exactly, what happened and what did you expect?
For instance if I do a Google search trying to research something I type in the search hit and hit go. I then click on a link in the search and let the page load. Look at the page to see if it has the answer I need. Then hit the back button and repeat the process with the next link. After about 1.5 to 2 minutes Firefox starts to load the page then the progress bar freezes about 1/6th of the way across the screen. If you wait several minutes the progress bar generally will continue to about 4/6th or 5/6th of the way across the screen then freeze again. If you turn WIFI off then on again Firefox will work for another 1.5 to 2 minutes and freeze again.
Same thing happens if you are on a web page clicking through links on the page. The problem occurs on all web pages.
Also more details on your wifi network would be helpful:
Hmmm, this is a difficult one--I work at the University of Washington, but not with the IT department that manages the technology infrastructure. So I don’t have a lot of technical details. Basically (among other jobs) I do the phone support for the Campus maintenance division. I support 250 to 300 users. While I do not have a lot of the specifics I will do my best to give you a general idea.
The best way to think of the UW is a small city. We have about 45,000 students and somewhere between 20,000 to 30,000 staff plus visitors. On any given day we can have 80,000 to 90,000 people on campus all of which are capable of using the WIFI network. So when I say we have a high volume WIFI network it is extremely high volume.
I noticed the problem with Firefox before and after spring break, but did not have the problem during spring break. WIFI usage would have been way down during this time because there would have been fewer people on campus. So the problem only seems to occur when volumes are very high.
I had a meeting with a UW-IT rep several months ago and he explained that the 2.4 network was near capacity some places on campus, but the 5.0 network had plenty of bandwidth on it. I think most of the phones I have been using work on the 2.4 network, but the Note 4 works with the 5.0 network also and has the same problem. Additionally all other programs work fine with WIFI so I do not think capacity is the issue.
Also I know Firefox itself is not the issue because it worked during spring break and it works on the cellular network. So some combo of the high volume network and Firefox seems to be creating the problem. Maybe has to do with how Firefox handles things when capacity is reached or exceeded.
As another side note I did not have the problem with my home network, but I was only using 2 phones at the time.
It sounds like you are technical since you have done so much testing. Please file a bug with the steps to reproduce at:
I have some technical skills, but really I am just good at research. I will do my best with the bug report :)
As for downgrading (which we DO NOT recommend & support since older versions don't have security fixes!) you can install an old nightly from:
I will try to work my way back to see if I can figure out what version of Firefox the problem started with.
Please let me know if you have any ideas or need any additional info.
Thanks!

Yahoo toolbar isn't compatable with ff 5.0, how do I revert to the previous version of firefox?

I just installed ff 5.0 & I'd like to go back to the previous version

See [[installing a previous version of Firefox]].
Possibly at some stage Yahoo will release an update to the toolbar so it works with Firefox again.
Update Note Yahoo toolbar is being made compatible with Firefox 5, and it was hoped to have been done by 21st June. ([/forums/contributors/707024?last=40411#post-40357 see] ) Yahoo toolbar is therefore likely to become compatible very soon, if not already.

How do I return to the previous version of Java?

After the latest Apple Update I have
After the latest Apple-Update, I use Java 6 Update 24 for Mac OS X 10.6.
If I try to upload the files in Safari and clicking the button for the upload, the window don't open to select the files.
If I try the same with Firefox, sometimes it works, sometimes not.
It is possible to get back to the previous version (perhaps Java 6 Update 22) and how?

Same probs here! Cannot acces drop-down menus in ebay, it screwed up my email and I can't access links, other stuff too! I thought these guys were reputable? And they want to drop support for the older version? NOT REAL HELPFUL! PLUS, YOU HAVE TO JUMP THRU HOOPWS TO DOWNLOAD OLDER VERSION, INSTEAD of putting access to it on the SAME page as the groovy new FF 4! C'mon guys! Can't you see this thing is not READY yet???? -Al McD.

How can I return to a previous version of Numbers? Or how can I have all my sheets show on a column on the left hand side, as in the previous version?

I updated my Numbers for Mac only to find out that there are several changes that make it less appealing for me so far (and I don't think it's only the learning curve). Questions: a) can I somehow edit the location of where I can find all the sheets (right now they are on top of the page, and you can't see all of them listed at quick glance but must scroll/arrow through them) I have in that spreadsheet? In the previous version they were all easy access on the left hand side.
Or b) can one go back to a previous version of a program somehow?
Thank you for any leads/answers!

can I somehow edit the location of where I can find all the sheets (right now they are on top of the page, and you can't see all of them listed at quick glance but must scroll/arrow through them)
On my machine I just hit shift-command-j (the keyboard shortcut I assigned in System Preferences) and a list of the sheets in the current document pops up:
I type a number from the list and jump immediately to that sheet. The hands never have to leave the keyboard.
(This particular document had a sheet named for each month. But the sheets in your document automatically will be listed instead.)
This is done via a Jump to Sheet Automator Service (Dropbox download). To install just doubleclick the .workflow package and (if needed) click 'Download Anyway' in System Preferences > Privacy & Security.
Installation will cause a new item to appear in your Numbers > Services menu. Then, if you want a keyboard shortcut, go here in System Preferences and add one:
You can rename or remove the service by holding down the option key in Finder and choosing Go > Library > Services. You can also view the AppleScript contaned within the service by opening the .workflow package in Automator.
Note, also, that in Numbers 3 you don't have to use those left-right arrows upper right to slowly scroll left-right to the sheets that are out of view. Just move your cursor up to the "band" with the "tabs" and drag left or right. That's much faster than using the arrows.

How can I go back to previous version of firefox cause 4 sucks and I am going to have to go back to internet explorer?

This version is horrible, and I want to downgrade back to previous version if I can't then I am going back to internet explorer, the search engine is an aberration...just trying to perform a search for hotmail sign in page and had to click on have a dozen responses before I find the one I want where before was right there at the top. If I cannot go back to a previous version, just tell me so I can start using internet explorer, it is horrible as well but at least search engine was not as frustrating to use!!!!

To downgrade to Firefox 3.6 first uninstall Firefox 4, but do not select the option to "Remove my Firefox personal data". If you select that option it will delete your bookmarks, passwords and other user data.
You can then install the latest version of Firefox 3.6 available from http://www.mozilla.com/en-US/firefox/all-older.html - it will automatically use your current bookmarks, passwords etc.
To avoid possible problems with downgrading, I recommend going to your profile folder and deleting the following files if they exist - extensions.cache, extensions.rdf, extensions.ini, extensions.sqlite and localstore.rdf. Deleting these files will force Firefox to rebuild the list of installed extensions, checking their compatibility, and reset toolbar customizations.

How can I re-download the previous version of Firefox. I have lost most of my add-ons with 4.0 including my password manager. This is a calamity and I've changed my default browser from Firefox. Help!!!

The problem is very simple. As soon as I downloaded Firefox 4.0 I lost my add-ons. The add-ons were the reason I have been using Firefox for several years. This seems to be ludicrous. The new version should be able to manage integration of existing add-ons or the Firefox team should have provided the add-on authors with advance technical information before releasing 4.0 to the world.

An alternative approach is to keep Firefox 4 and install the portable version of Firefox 3.6 on your hard drive. The portable version will be totally independent of the main version and can be used when you want to access the bank site. You can get it from http://portableapps.com/apps/internet/firefox_portable
