Firefox supportforum

I currently have a Windows 7 PC with Firefox version 112.0.2 and normally use the EXE files from Mozilla's FTP site (ftp.mozilla.org/pub/firefox/releases) to upgrade Firefox.

With Mozilla's decision to move Windows 7 users on to the ESR branch of Firefox I was looking for the best way to install the ESR version using EXE/MSI files. In this regard I have the following questions:

1) Is it best to first install the standard Firefox 115.0.3 EXE (last standard Firefox for Windows 7 users) and then the 115.1.0 EXE (first Windows 7 ESR Firefox)?

2) Would doing the above method cause any conflictions?

3) I read a while ago that the ESR version is a separate install that can run in parallel to the standard version, if this is true would it be ok to uninstall the standard version after the ESR install to not leave vulnerable versions on the system?

4) As the latest ESR version is 115.5.0, if the above method is ok. After installing the standard 115.0.3 should I still install 115.1.0 ESR or move straight to 115.5.0 ESR?

5) When moved onto the ESR branch can you jump versions or do the updates have to be installed in order?

My apologies if I am being a numpty, but I have been using Firefox for many years without issue, and recently (possibly after an update, but I cannot be certain), it has started to randomly freeze. I am running Ubuntu 22.04, and Firefox 119.0. I have demonstrated to myself that if I open a web page with links (but not always), and click on the link, I may still scroll up and down the page, but the mouse cursor never seemed to recognise the hotlink, and doesn't jump to it. The links will work on Chromium. I initially tried resetting the browser, thereby losing all my open pages, but that didn't work. That also removed all extensions ("all" two of them) and that didn't work. Firefox is now pretty much unusable. Any help to resolve this would be appreciated, as I cannot find any solutions online, and it seems I am not alone with this issue! Many thanks,

Yo, Linux sysadmin here and been using Firefox forever.  Surprisingly I have this ancient 12 year old System76 laptop that I use for nearly everything (got a newer Lenovo that I been meaning to switch to but no time).

Using Debian 12/13 with Gnome 43.6/X11.  Can't quite figure out this issue though.  Besides being a sysadmin, can have other side jobs/projects going on as well, so can have 5-10 windows open in different workspaces, sometimes with hundreds of tabs all together (big fan of the Auto Tab Discard add-on and about:memory Minimize Memory Usage to keep performance up and resource usage low).

Been noticing this issue for the last few versions where suddenly, after random amount of Firefox uptime (can be after days of perfect performance) my keyboard input aka typing gets extremely laggy, like 30 seconds behind for all keystrokes, except: Ctrl-F instantly brings up the Find in Page bar, and Ctrl-C instantly copies to clipboard.  Ctrl-V, however, 30 seconds lag, Ctrl-A also....  Mouse is fine though and can right-click and paste instantly or use other menu options.  Happens anywhere in Firefox too: in address bar, in the find text box, in the preferences, in my saved passwords, haven't found a place with no lag.

Have searched around for some hours now and only found suggestions to disable accessibility service, but accessibility service has already been disabled for a while now.  Everything else in my Gnome desktop session is running fine.  Restarting Firefox temporarily solves the issue but is highly annoying and interruptive with as much as I have going on sometimes.  Due to timing randomness, starting Firefox without certain add-ons is impossible as I can't spend days at a time without any of them.  Just have to open a text editor and type what I need to in there, then paste with mouse, until I can find a good stopping place to restart Firefox.

Have included most of the info from about:support in the Troubleshooting Information.  Spent quite a bit of time looking at all my modified preferences, nothing popped out but if there's something you think I could include to help, let me know. Thanks

I am running Mozilla Firefox on two laptops each of which is running Ubuntu Linux 22.04 LTS. In both cases Firefox is installed by the Debian/Ubuntu 'snap' program.

On the first of these two machines -- the only less frequently used or updated -- "About Mozilla Firefox" shows that I am running:

Firefox Browser 118.0.2 (64-bit) Mozilla Firefox Snap for Ubuntu canonical-002-1.0

On this machine I see this on the command-line:

Calling: '$ ls -ltr /snap/slack' shows that the current 'snap' is 113, created Nov 1. The date on the symlink between '/snap/slack/current/ and '113' is Nov 9, suggesting that I was prompted to run 'snap' and upgrade Firefox on Nov 9.

On this first machine, Firefox is performing as intended.

On the second machine, however, a more recent version of Firefox is blurring photos on at least one important website. (As far as I can tell, all other rendering of web pages is satisfactory.) The information on the second machine is:

Firefox Browser 120.0 (64-bit) Mozilla Firefox Snap for Ubuntu canonical-002-1.0

From this machine's command-line:

$ ls -ltr /snap/firefox total 0 drwxr-xr-x 7 root root 201 Nov 6 18:34 3358 drwxr-xr-x 7 root root 201 Nov 16 17:34 3416 lrwxrwxrwx 1 root root 4 Nov 23 21:37 current -> 3416

This suggests that Ubuntu build build 3416 on Nov 16 and that I was prompted to install it on Nov 23. That's 2 days before I am writing this bug report, and that duration is roughly the duration in which I have observed this blurring problem.

The problem occurs at this website:

https://www.washingtonpost.com/

On this page, the photos are all in sharp focus and everything else is being rendered as expected. See: Screenshot from 2023-11-25 17-02-46.png

However, if I right-click on any URL or photo on the home page to take me to the page for a specific article, I get a blurred photo. Example:

https://www.washingtonpost.com/health/2023/11/25/zoom-fatigue-brain-heart-effects/

Note how blurry this photo is. See: Screenshot from 2023-11-25 17-03-39.png

This blurriness does *not* happen with the older version of Firefox on my first machine. My inference is that there was some change between 118.0.2 and 120.0 that is failing to correctly process data coming from this website. Suggestions?

Long time Firefox user on Linux. Password manager has never saved passwords, but I just lived with it. Recently, I tried setting a primary password, and now I can't log in to eBay, or Mozilla. On eBay, I type my user ID and the continue button is greyed out. On Mozilla, now I get "Local storage and cookies are required", but I DO have them turned on. I tried to change/set the Primary Password, and I get "Unable to change Primary Password". Is there a file protection/privilege problem? How can I track this down? Thanks, Jon

Hello

again after upgrade this time version 119.0.1 to version 120.0 the behaviour changed to store downloads. This time I directly modified the settings of applications, their type and which action I expect. Again problems and files are stored elsewhere. Once again modifications and it seems to be fixed.

It seems that this part of Firefox is modified too but I'm not sure. One download is still running and the file and the temporary part exists but not in the specified base directory. The other ones are working as result of my second approach.

Any other experience concerning download and where to store?

Kind regards

 Stephan Albert

Up to four or so days ago I was able to fire up my Linux and Firefox and had immediate access to both Gmail and Calendar. Now I am requested to sign in every time, are offered a Shareable Calendar (for which I have no use) and get a notification in my cell phone reporting a new login. Also, WhatsApp Web is requiring to link with my phone every time I want to use it in my laptop.

I'm using Firefox 120.0 and this behavior appears to have started after the upgrade. I have also Vivaldi installed and its operation with the above pages is normal.

This is most annoying. Have security rules been changed? Am I doing something wrong? Will appreciate any help you can provide.
