Several weeks ago, because it seemed to be a Gmail-tab-only problem, Firefox Support advised us to contact Gmail Support.

It is now clear that the problem is with the Firefox browser. The attached screenshot shows an example of an affected tab.

Please fix this. Multiple versions of the same tab waste RAM and other memory, especially on a limited-memory device such as a laptop.

Hello! Something in my Firefox installation seems to be making several Google network (google.com / forcesafesearch.google.com / www.youtube-nocookie.com / m.youtube.com, and a couple of others) calls shortly after launch. I have a DNS sinkhole, so that is how I can see.

I have a few reputable extensions (or should be, from EFF, Firefox itself, or Ublock Origin), but it also happens in safe mode. I went through a good chunk of this: https://support.mozilla.org/en-US/kb/how-stop-firefox-making-automatic-connections and still the calls occur

I am on Windows 10, with FF v93.

Thanks very much!

A very serious bug in all Firefox browsers (it's been around for several years!). If you open multiple tabs (many tabs) in your browser, virtually all settings will not work, e.g. you won't open Options, Menus, various tasks, extensions, won't save your bookmarks, and many other problems. Although the browser opens a page and the Tab works! But everything else is NOT WORKING, even in Safe Mode or Troubleshooting Mode! I've reported this many times: No developer help!

I've been having an interesting problem with Firefox for the past couple of months regarding only Soundcloud, where after the first visit to the website it won't load, giving a generic "Sorry! Something went wrong" screen. Firefox will continue to not load the site correctly until I clear the cookies and the cache, which works but only for one visit, and as soon as I close the tab and open soundcloud again or refresh the tab the problem comes back. I have disabled all of my extensions as well as enhanced tracking protection when testing. A firefox refresh also did not solve the problem. The only way I can get the site to behave normally is when using private browsing.

The console is filled with errors regarding javascript files (source URI is not allowed in this document).

Thanks

It took years to perfect my userchrome to make FF look exactly how I want. Once 91+ came out it wasn't even a question of fixing the floating tabs and condensing the height and menu spacing (though I tried all of it) but my own codes stopped working properly - I had code to set the background colour of menus/bookmark menus and when I upgrade they were the right colour but with thick white borders around them. This was more important to me than the floating tabs and I immediately downgraded to 90 where I've stayed. Can anyone help me figure out how to get MY codes to work with 91+ and/or to work together with the other fixes out there (tabs, condensed menus etc)??

Below is how my userchrome looks and attached is how my current set up looks. ANY advice is appreciated. THANK YOU.

This problem has been happening for a long time now. When I'm playing a playlist in YouTube, and YouTube automatically select the next song in the playlist, the song stops and I get the message "Playback Paused because your account is being used in another location". This problem ONLY happens in Firefox and with this playlist scenario. If I select the song manually in the playlist, the song will play just fine. I've used other browsers Chrome and Microsoft Edge and DO NOT have the problem in there so I know my account isn't being used in another location. I've tried using multiple PC's/Laptops and both Windows 7 and 10 and the problem always only happens when using Firefox. I checked the About section in Firefox and it's showing Firefox is Up To Date.

Hello together.

I'm experiencing the same problem as discussed in this cases that is not solved yet: https://support.mozilla.org/en-US/questions/1312836 https://support.mozilla.org/en-US/questions/1333547 https://support.mozilla.org/en-US/questions/1321038

Symptoms: After FF starting it loads pages fast enough. After several minutes of using pages start be loading very slow. Loading slowness increases until it becomes blocked continuously. Reload button has no effect. I tried everything from here: https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can - No effect.

Work around done: When windows is loading in Safe Mode the problem disappeared. If I disable Windows Defender Firewall the the problem disappear and appear after firewall enabling again in several minutes (same as after FF restarting) When I go to <current network settings> and switch Network Profile from Public to Private or from Private to Public the problem disappear but goes back just in several minutes (same as after FF restarting). Windows 10 Restorehealth has no effect, and reports that everything is OK with system files (DISM.exe /Online /Cleanup-image /Restorehealth ) The most strange thing Windows 10 In-place Upgrade has no effect.


I found out the core of problem is that Windows Firewall is blocking FF internal interprocess communication on local TCP ports. Yes, you would say it is not possible and firewall doesn't affect local port communication but in my case it is a fact. I used the ProcessMonitor from Windows Sysinternals, and Windows Defender Firewall with Advanced Security log. Screenshots shows this fact. On first two lines from Firewall log you see a Local Port Communication blocking, on ports 1401 and 1400. Next Screenshot from ProcessMonitor shows (see blue colored lines) that it was exactly FF communication, where I was trying to reload a page several times.

Any ideas what to do with it? It seems like Microsoft’s way fighting a concurrent web browsers, but I hope it isn’t.

Now I use FF version 94 but the problem starts from 88. I was trying FF downgrading to version 75 with no effect.

Firefox seems to constrain the maximum size of the ".sqlite" file in "storage/default" in "~/.mozilla/firefox" to 10% of the free space of the partition containing the home directory of the user. I need to let the ".sqlite" file grow very large, even larger than the free space of the partition containing my home directory. Therefore, I need the following two points.

1. I would like to disable this 10% constraint. 2. I would like to place this ".sqlite" on an external USB drive (or USB stick) without moving the entire "~/.mozilla/firefox" directory to the external USB drive.

The path of this ".sqlite" contains an enigmatic alphanumeric string and hexadecimal digits, which differ from user to user and from machine to machine, and which may be inappropriate to be exposed to the public. So, I refrain from showing the exact path. Instead, I will describe the path.

The directory "~/.mozilla/firefox" contains a subdirectory whose name ends with ".default-release", which in turn has a subdirectory "storage/default", which still in turn has a subdirectory whose name starts with "moz-extension+++" followed by hexadecimal digits and hyphens (but not followed by "^userContextId"), which still in turn has a subdirectory "idb", which finally contains the file whose name ends with ".sqlite".

The following is a diagram to describe the path. Directories are separated by / as common on Unix-like systems unlike Windows. A sequence of three asterisks (***) indicates an omission of enigmatic string.

   ~/.mozilla/firefox/
     ***.default-release/
       storage/default/
         moz-extension+++***/  not followed by ^userContextId
           idb/
             ***.sqlite


Firefox seems to constrain the maximum size of this ".sqlite" file to 10% of the free space of the partition containing the home directory of the user.

I replaced the "idb" directory with a symlink named "idb" which points at a directory (which is also named "idb") on an external USB drive. That is, I deleted the "idb" directory from the partition containing the "~/.mozilla/firefox" directory, and created a symlink named "idb" in the place of the old "idb" directory.

Then, I successfully let Firefox write data into the new ".sqlite" file on the external USB drive. However, Firefox continues to constrain the maximum size of this ".sqlite" file to 10% of the free space of the partition containing the home directory of the user. Even after the diversion by symlink, the basis of the constraint is still the partition containing the home directory of the user (instead of the external USB drive), of which 10% is the max size of the new ".sqlite" file residing on the external USB drive.

I like neither the 10% constraint itself nor the basis of constraint being the partition containing the home directory of the user.

How can the 10% constraint be disabled? I would like the only limitation for the size of the ".sqlite" file to be the free space of the external USB drive.


By the way, for those who want to know why I care about this ".sqlite" file, I will explain as follows. There is a certain download manager which is an addon or extension of Firefox. In its multithread mode, this download manager divides the desired file into several parts, and downloads all the parts simultaneously. In certain circumstances, the multithread mode is several times faster than the single-thread mode. This download manager downloads all the parts of a file into the ".sqlite" file first, and then assembles them into a final big file in the Downloads folder or whichever directory that the user specifies.

In my use case, 10% of the free space of the partition containing my home directory is too small to receive big files. I wish this download manager could download the multi-parts into an external USB drive in a manner that Firefox does not impose any constraint. However, this download manager cannot let the user specify where the multi-parts should be downloaded to. It downloads the multi-parts into only the ".sqlite" file and nowhere else; and Firefox imposes the 10% constraint on the ".sqlite" file. The user can specify the destination of only the final file assembled from the multi-parts.

Anyway, I need to disable the 10% constraint. But how?

Thank you in advance.
