Firefox Community Forum

After every update, Firefox starts to a blank screen and will not start loading the webpage url put in for over twenty minutes to a half hour. During this time other browsers on my Win 10 PC load immediately so it is not a network issue. It is Firefox. When I see that an update is pending I hesitate to do the update because I know I will lose the use of Firefox until it is ready to respond. It just hangs with "loading X.com" showing at the bottom left of the blank screen. I have been using Firefox for a long time and in the past year or longer it has become very unreliable. There are also instances where without an update it will do this and the only way I can get it to work is to clear the cache and the history through settings. What is going on with Firefox! (And lately there is an update every couple fo days!

latest versions of firefox (now at 140.0.1) keeps opening onto my 2nd monitor which is off - how to stop it doing it. Tried making new profile which works for awhile, but sooner or later they all bump it to the 2nd monitor and it never comes back - tried moving to primary and closing it there, but next time back on #2. Open 2nd window while first is on primary, and that goes to 2nd monitor...

Hello.

I use Firefox on an computer with Ubuntu, (installed as snap) and have noticed that since the update to version 140 (specifically, version 140.0 canonical-002-1.0), closing a tab causes a noticeable delay : that is, upon any action that would close a tab (clicking on the cross, pressing CTRL+w, or middle clicking), there is a delay of about 200 to 300 ms before the tab is actually closed.

However, during this delay, the window still responds to inputs, leading to rather annoying situations. For example, during regular usage, I usually open a great number of tabs. When I am done with browsing, I close them, by repeatedly clicking the cross button on the tabs. It used to be that the tab under the cursor would immediately close, then the next tab would slide under the cursor, and I would click again to close that one, etc.

But now, when clicking the cross button, the tab is not closed, and when I click again after a small delay (because of muscle memory), the tab is still there. This cause the two single clicks to be treated as a single double-click, which for some reason puts the window in full-screen mode (but only with the snap version; I'm not sure what's going on here).

When using CTRL+w when closing tabs, the delay is still there, but the inputs are correctly handled. If I press CTRL+w three times at the usual rate, I can see the three key presses, then nothing happens for a few instants, then the three tabs close at the same time (i.e. the delay is from input to tab close, not from tab close to other tab close).

This behaviour is completely absent on Firefox (also version 140) on my windows computer.

This delay does not appear when creating tabs, and it does not occur either when closing the window or when closing the last tab in the window (leading to an amusing situation where shutting down Firefox is actually faster then closing a tab). These operation keep going at their previous speed, immeasurably fast to the human eye.

Navigation does not appear to be meaningfully slower than before the update, and the CPU/memory usage is very reasonable.

Curiously, this appears to be a fixed delay. Closing an empty tab takes the same time as closing a very busy one. Closing a tab when there are five takes the same time as closing a tab when there are thirty.

This issue makes browsing feel incredibly sluggish.

Is there a solution for this problem ?

Edit 1 : I have tried to run Firefox in troubleshoot mode, but there was no difference in behaviour. Edit 2 : Fixed typo. Edit 3 : Added exact version. I also tried to refresh Firefox, but the issue remained. Edit 4 : The problem is still present in version 140.0.1 canonical-002-1.0. Edit 5 : The problem is still present in version 140.0.2 canonical-002-1.0. Edit 6 : As of version 140.0.4 canonical-002-1.0, the problem seems to have been fixed. Thank you.

Firefox has just introduced wallpapers for browser home page. I cannot get it to work. It's either cropped too small or pixilated, is there a setting I need to adjust, or a particular image format? So that it looks ok.

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?

When assigning a URL to the mediaplayer object it started appending the current path to the URL. Did not do that in prior version. You can see it automatically puts the current browsing URL and then the URL that is assigned. So the file will not load.

I am using Firefox on Win 11, recently I have noticed a weird problem, on Ebay for example when a listing uses a drop down selection box for sizes, amounts etc none of them work for me, I click on the box and down arrow but nothing. I also went on to the Vodafone site to top up my phone but I was unable to do it as the drop down box to select the amount was empty. I have tried clearing my cache and even reloading Firefox but nothing seems to work, I just tried using Edge as well but its the same, suggesting that its maybe something to do with my settings?

Every time i load a page i have to quickly click on the link. If i don't it will not load. Every website that has a drop down menu wont allow me to click. In order to click anything i have to refresh the page and click the link before it fully loads or else it just wont register. And it wont register across the entire page. Can't open in a different tab, cant do anything.

Doesn't happen with anything other than your browser.

I want to keep using your browser but its becoming incredibly annoying and i often have to jst say "fuck Firefox" copy the link to any other browser and it works perfectly.

I updated to the newest version of firefox the day it released and everything was fine until today 7-4-25. I logged onto my pc and it would not open. Task manager doesnt even recognize it as a program. So i restarted, still did not open, i refreshed with the installer still did not open. Set as run as administrator it opens but i get a white screen with all my tabs crashed out my settings are gone in firefox and i cant open anything in the options at all below is how my firefox looks no matter what i do. I have gone into command prompt and everything did a flush i went to check to see if the launcher was enabled it is enabled in the actual config but it comes up as disabled in the support page (and thats when I can get those to open they dont open all the time) I uninstalled and reinstalled three times. and yes i did a fresh install.

how my firefox screen now looks nothing works.....

When I log in to my account at https://my.noip.com/ and display my dashboard there is a constantly displayed banner across the top of the page that says:

FireFox prevented this page from automatically reloading - Allow

when I click Allow the page just reloads with the same banner

What setting can I change to get rid of this banner?

I reinstalled windows on my pc after syncing all my browser data (bookmarks etc) everything but some bookmarks, i have 4 folders and 2 of them had all that was in there and the other 2 where empty is it possible to get them back somehow?

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

Just switched from PC to Mac and miss the Page Up, Page Down, Home and End buttons. Wondering if there's a Firefox addon or extension to add these functions to a Macbook. I've searched but not found anything. I know I can't be alone in wishing for this!

(I am aware of using "Fn" and the arrow keys on a Mac to do page up and page down, but they are opposite sides of the keyboard and require both hands to scroll by page.)

Any time I allow a website to use my location on my home computer, it places me in a suburb in Las Vegas. However, I live near Seattle. This happens on multiple websites including Google Maps and Uber Eats, and on other browsers my location is correct. I'm not running any VPNs or proxy servers, I've verified that my IP address is linked to my correct location, and I've deleted all cache and cookies ("Everything" for time frame) from my history. Is there a way I can have an accurate location again?

I use a MacBook Air running on Sequoia 15.5. Firefox was updated several days ago to 140.0.2 (aarch64).

Since yesterday, Firefox has repeatedly stopped running. (It might have started sooner, but I didn't use the computer over the long weekend.) It won't load pages. Sometimes I get the spinning wheel. Usually, I have to force quit.

I've cleared the cache, restarted the browser, and restarted the computer repeatedly. Restarting the computer sometimes helps. Now is not one of those times.

Also, the About Firefox window is open, and the Checking for updates . . . wheel keeps spinning.

There are no connectivity issues otherwise with my computer or other apps.

Does anyone know why this is happening? Do I need to go back to the last version of Firefox? Uninstall/reinstall?

Firefox tabs keep crashing randomly and sometimes the entire thing just crashes and the browser has to be restarted completely. I' have already tried: Updating Firefox Completely reinstalling firefox after I removed all App Data of it. Updated all the drivers that were possible to update. Installed newer codecs (H265)

Nothing so far worked to solve this issue.
