Firefox Support Forum

Since the task limit option seems to have been obliterated? I believe the many more "programs" and the events they create for windows to handle is causing all sorts of virtual memory problems. Changing win10 advanced system settings from performance for programs to background services seems to have restored Firefox performance in my case, see: 10 advanced system settings win10 advanced system settings performance programs vs background services Is there an about:config option that would allow one to achieve the same "programs" limiting option as before? This laptop has 16 gig of memory and I used to successfully have even better Firefox performance with windows virtual memory turned off, but eventually I would get crashes. I can understand why Firefox was modified in a way to better localize the source of crashes, but in my case it has degraded performance. Thanks Mozilla for a great product I have valued for years!!!!

Everything worked normally for me for 2 years, but recently i decided to reinstall windows. So i did it, downloaded firefox on raw system and now i get this error on some youtube videos. I tried everything i could find but nothing fixed this issue. It pops up with firefox account, without it, in private vindows, in regular ones, with addons, without them. I tried reinstalling firefox, i updated every driver, i use google DNS, but it still doesnt work. In edge, chrome etc. theese videos play fine

Greetings everyone,

I accidentally double clicked on "Downloads" after accessing the "Tools" menu so all of my downloads in the "Downloads list" is now gone... :(

I know that the actual files aren't deleted but I can no longer see the location of the files I've recently downloaded :( :(

Thank you for any help!

When I switch from one tab to another doesn't matter the webpage the page adjusts the content on the tab. For example I was on youtube and switched over to gmail and it adjusted the screen and when I switched back to youtube it did the same on youtube. I wasn't zoomed in or anything. I was just on the tab and it was fine and looked how it should but as soon as I switch to another tab it does it on that tab and then will do it again when I switch back to the tab I was on originally on. I'm on FF vers 113.0.2 (64-bit).

Hello,

My bank's website has a 2 page verification process for logging on. The first page is for the User ID and the second page is for the password.

Until just a few days ago, I could enter the first letter of my User ID into my bank's website login field, and FF would auto-fill the rest. Now when I enter that first letter, nothing happens. I then have to look up this info before I can continue. Luckily, the second page (for the password) is working just fine.

If I remember correctly, there has been a recent FF update. This new update may be the source of this issue.

Please help!

Thanks, Andre'a

Hi all Gurus,

Is there anyway or what is the policy that I can configure to disable the "New Tab Ctrl+T" function on the menu please? Attached image.

Hi there! My Website layout not properly show in Firefox browser as shown on other browsers like chrome, apple browser and others. page width shows to short. Is that browser issue or my website? Note: I used some WP plugins in my website.

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 :-)

There are many mainstream websites that have stopped functioning in firefox that work perfectly fine when switching over to brave and enabling scripts

these are not obscure sites, they are sites for privacy protecting entities hence the lack of function on firefox is perplexing

how do we make these sites work in firefox again to save the switching to brave?

Firefox is Generating Error Messages. I use a password manager and know the correct ID and Password is being used. Twice recently, I have had to resort to Microsoft Edge to get around denial of access by Firefox. What do I need to do with Firefox to eliminate the denial of access of a website?

I make themes for themes for firefox using firefox colors extension. I want to know how to change the text colour, background colour, etc of right click menus ( see image attached.

I would like to add the bookmark tree to my Fickle theme so the colors used can also be seen when looking at my bookmarks. I would gladly ask permission from the person who created the bookmark tree extension and try an see if his extensions could list the bookmarks in the same blue/yellow colors of Fickle. I hope it can work and thanks for any and all help. Rob

Hi.. Last few upgrades, Firefox browser will not keep passwords to bookmark sites. Have to go thru a lot of trouble to sign in to any password sites that is not saved any longer in Fire fox browser.. Tried all kinds of setting in Firefox and disable our virus programs and win 10 items to find a way to save pass words. Google and other browser will save the pass words.
