Need some help with Firefox crashing. System: Windows 8.1 64 Bit instilled on a Samsung SSD, 24 GB free space, 24 Gigs RAM, Firefox installed on conventional HDD (G:\) drive, 1.03 TB free space. This has been the standing configuration for many years, working with no problems.

Problems began with FF update 111.0. Any attempt to download files (.jpg or .pdf) would cause the “save” button to freeze, and after a seconds FF would crash. If an attempt was made to change a setting FF would again crash so quickly it was impossible to attempt any changes. Oddly enough, FF update 111.0.1 fixed the issue (or so I thought) and things returned to normal. I assumed whatever caused the problem had been fixed.

Unfortunately, every update beyond 111.0.1 reverts back to the same freezing and crashing behavior. I have attempted the following with all updates above 111.0.1 in an effort to correct the issue. So far nothing has worked. BTW, Brave and Chrome work just fine.

Cleared out all cache and cookies. Changed download folder Opening in safe (trouble shooting) mode Clean install(s) Disabled hardware acceleration. Putting the entire program on C:\ drive (apparently the newer FF installer does not allow custom installations any more). Checked and updated all drivers

Currently I have disabled automatic updates as none of them have the same freeze/crash issue. I am out of ideas and would certainly be glad to get any advice. At this point Brave is going to be my new default browser. Yes, I know 8.1 is no longer supported but I am not in a position to replace this PC at the moment.

I've installed a new version of Ubuntu Linux and - as recommended on this page's FAQs - backed up my firefox profile, than copied it into the profile folder on the new os. Now Firefox tells me "You've launched an older version of firefox" and forces me to create a new profile :( Also loading the old profile in "about:profiles" leads to the same result

How can i restore at least my passwords? (When i try to copy only 4.db and logins.json from the old to the new profile, i get the same result)

I can't find an "import old profile"-function anywhere...

My e-mail address changed, but the old one keeps popping up. I need to ELIMINATE the old one and use ONLY the new one. I've told various organizations, businesses, etc., to make the change. I want Mozilla Firefox to ELIMINATE the old one and use ONLY the new one. Help!

The download is that I am always movies on the transfer to a good comedy and show us movies because of the news , e-mailed, browser Firefox Android.install and migrate etc

Summary of my current relevant software/hardware:

FireFox (UK): 113.0.2 (64-bit)
Windows 10 Pro(UK): 
 Vers.: 22H2
 Installed on: 2021-01-23
 OS build: 19045-2965
Lenovo (laptop): 
 ThinkPad X1 Extreme Gen 3
 Processor: Intel(R) Core(TM) i7-10750H CPU @ 2.60GHz 2.59 GHz
 Installed RAM: 32.0 GB (31.8 GB usable)
 System Type: 64-bit operating system, x64-based processor

My problems with FireFox 113.0.2 started when I began to download some Affinity V2 videos. Some of these were rather large (over 500MB) and I noticed that several were being downloaded at the same time (which was no surprise). However, after sometime I noticed that only one of the videos was completely downloaded and the others were just stopped. Then, when I looked at the task manager the number of FireFox instances was increasing: ...,5,6,...18,..

Of course, I thought I could fix the download process but all my efforts failed; e.g. after a restart of windows and execution of FireFox the same videos were still in a "hold" state and many instances of FireFox were being executed. After a frustating night of failures I finally decided to restore an older FireFox using my Acronis backup/recovery software. My last Aronis backup of my entire system was made on 2023/04/07 with the most recent version of FireFox at the time which worked fine when downloading several large video files at the same time.

I only included the C:\Program Files\Mozilla Firefox' in the restore since I have installed a rather large number of new apps and updates after 2023/04/07. This also failed -- my add-ons, bookmarks, etc. in this restored version were all missing and before I could stop the recovery process, the restored FireFox was updated to the latest as of today (2023/06/01). And of course the problem had not be fixed.

So finally to my request: What directories, files do I need to restore, from the 2023/04/27 backup with all of its features at that time -- this is important, and how do I stop it from upgrading to a newer version?

I would be glad to provide additional information if needed :-)

Each and every time you install an upgrade on Firefox, your profile vanishes. So I questioned on how to save my profile and I found a nasty solution where you have to close Firefox because of a stupid empty file named parent.lock which happen to be empty on the 2 cases I checked. I did not sniff in the restore constraints yet... What a mess ! Looking at the frequency the Firefox's upgrade arrives, it would be advisable to automatically preserve the user's parameters. Alternately it would be a good thing to have a save/restore function for Firefox's parameter.

I download anything over a certain file size, a couple of Mb, and Firefox pops up with this error "failed". I then must manually start the download from where it left of and it resumes this cycle of stopping and me starting.

I have a HP laptop 15-BA009DX with a Firefox problem. I noticed that the newest Firefox release takes one of my backed up bookmarks that I restore - causing the folders to "leak" the bookmarks out of the folders. The result is a list at the bottom of the bookmarks menu containing several hundred bookmarks. It seems to only happen when you restore a bookmark .json file. I Loaded the Extended Support Release (ESR) version on my laptop and discoveredf that it doesn't have this bookmark "leak" problem.

I tried to install the ESR version on my other (standby) laptop in place of the "regular" version to fix this bookmark folder "leaking" but the ESR version appears to not completely install. I can't go to any web page and I can't access the Tools > Options page. When I select the "Options" choice, it doesn't do anything. I have tried to uninstall and reinstall both the ESR version and the "regular" version several times with the same result. I frequently get an install error message similar to "VCRuntime140_1.dll not found - Reinstall can fix this".

I am familiar with computers but I'm not a techie. Installing this should be a no-brainer, but I am baffled why it won't correctly install and work.

Any Idea what is causing this problem? Thanks for your kind reply.

I have a large number of carefully organized Firefox bookmarks, which I backed up each time I logged off for the day, saving the most recent five. I imported these from my standalone backup hard drive to my new computer. Firefox couldn't restore them. Then I saw that for all five files, the listed file type was "Microsoft Edge HTML Document," so no wonder.

I have no idea how or why this happened or what to do about it. In theory, import into Edge and then export into Firefox? Given this incident and some bad past experiences, that prospect scares me to death. Any other suggestions, please? I would be so grateful for a way out of this.
