Since the last update Firefox sends the processor load through the roof. Both on desktop and on Android. For the first time since like version 7 I'm a bit disappointed.

What's up with this?

Firefox 139.0.4. version is also not good! Uploading videos to Youtube does not work with it! It does not move from zero percent! As I wrote earlier, the problem started with version 138.0.4. and is still ongoing! Uploading videos works with other browsers! I am waiting for the problem to be solved! If I wrote my letter in the wrong place, please forward it to the authorities! At the moment I could write a letter here, I can't really find a topic where this would be discussed! My OS Win10 64 bit. Thank you!

When I download Firefox initially I am able to set the home page the way I want with the shortcuts I use. After a few weeks the shortcuts disappear and the only way to get them back is to delete Firefox and reinstall. I am also not able to save bookmarks anymore. This has the same resolution methods.

This has happened 3 times already.

I own a website that has chat rooms for each of my advisors. As of 2 days ago they are all having issues. I have them login with Firefox but now asking them to use Google Chrome...............low and behold it works

Whats the issue as i believe it started with the latest Firefox update

Thanks so much

Sir/ Madam,

My mail checker extension isn't working right in Firefox. Extension Link I was able to find an error using Developer Options but I don't know if the error is even related to the extension or if it is even useful. If anyone would help me, I would be very grateful.

Firefox stopped working on my computer. Every time I try to open it I get an error message that says "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." I tried to uninstall and reinstall with no success. Our IT dept tried as well and nothing we have tried has resolved the issue. Thank you for your help.

Ok so I usually choose these option to remember history and from time to time delete Browsing & download history and Temporary cached files and pages.

Note: I have "Open previous window and tabs" ticked in general settings which also has a restore previous session option in the history menu. This brings back previous session with tabs etc as is when I close FF. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-51-cf2daf.png

I thought I could automate this on exit but don't think its working right. So I change the option to "use custom settings for history" and tick all three options:

Remember browsing and download history Remember search and form history Clear history when Firefox closes For "Clear history when Firefox closes" I ticked Browsing & download history and Temporary cached files and pages. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-43-b10213.png

The issue is the restore session option is missing and FF opens with all previous tabs gone. I am frankly not even sure what else is missing such as cookies, site data etc. Is this meant to work like so?

After updating Firefox yesterday, when I use the search bar, switching between my custom search engines can only be done via clicking on a drop down menu at the left end of the search bar and selecting one with the mouse cursor. Previously, I could select my preferred search engine by using the up or down keys to cycle through them while typing a search, then hitting enter when the one I wanted was highlighted. Having to switch from keyboard to mousepad while typing a search is really annoying, I found the old way much more convenient. Is there a way to revert this, and put the search engines back at the bottom of the search suggestions, where I can access them with arrow keys?

Also, when I search now, the search stays in the search bar instead of changing to a URL, and I have to click a little internet globe icon at the right end of the bar for it to show the URL. This is also kind of annoying. Is there a way to turn this off, and just set it to show the URL every time?

The setting works...in the way that if i quit Firefox, it'll not continue from the tabs and windows, but if i reboot my pc and open Firefox, I find myself the same place i stopped...even though i have that setting disabled. I found someone else with same issue on reddit and i did the same restarting the browser and refreshing and all....all to no effect.

When log in to some sites using Safari, it a text to me security logon code is requested, it will show up automatically on the site for me to "click" and insert.

is there a setting for this?

I only discovered the tab groups function within the last few weeks, and upon finding, I moved dozens of open tabs into organized groups. On using the feature, I noticed the ability to save and close groups and that I could recover those closed groups by using the arrow in the browser toolbar.

When I got to my PC this morning, my desktop had restarted or hibernated or something; when I started it up, Firefox was open which is unusual as I don't have Firefox set to open on startup - usually so I can restore sessions after crashes. All of my previously open tabs were open, but none of the closed, saved tab groups are visible. I cannot find any of the dozen or so closed tab groups and it appears I've lost easily hundreds of tabs.

I tried looking at the session backups but it seems because Firefox was open on start, it overwrote the previous session data. Is there any way to recover those saved groups or am I SOL?

I have autoconfig.js set up to run my own js file, see below. The intention is to change the keyboard shortcuts (shame that it's so difficult😃). It worked until a few weeks ago. Now it only partly works. C+J is fine. The other two succeed in deleting the existing command, and the shortcut key does nothing. Any ideas please?

// C+J = open downloads var element = document.getElementById('key_openDownloads'); if (element) {

 element.setAttribute('key', 'j');
 element.setAttribute('modifiers', 'accel');

}

// C+D = Duplicate tab var element = document.getElementById('addBookmarkAsKb'); if (element) {

 element.removeAttribute('command');
 element.setAttribute('oncommand', "duplicateTabIn(gBrowser.selectedTab, 'tab')");

}

// CS+N = move tab to new window var element = document.getElementById('key_undoCloseWindow'); if (element) {

 element.removeAttribute('command');
 element.setAttribute('oncommand', 'gBrowser.replaceTabsWithWindow(gBrowser.selectedTab)');

}

I am not sure why every time I go to print something, it takes the color blue and turns it gold. I have used other browsers like Edge to print and it does not do this, only while I am using firefox. I have tried to set the color management mode to 0 and to 1 and neither of these options have worked. Is this a problem with the newest update or is there a setting that I am missing?

Suddenly getting persistent "Gah. Your tab just crashed" error message this week; running Windows 11 on a Lenovo X1 Carbon 12th Gen laptop; I have run Firefox in Safe mode, disbled multi-process tabs, turned off h'ware acceleration, cleared cache and cookies, turned off BitDefender, Refresed firefox, updated firefox and windows, checked for malware, reinstalled Firefox, and attempted to create a new Firefox proficle (didn't run), all to no avail; attempted to use mozregression, but I don't have the skills. Would be glad of any help! Thanks
