Firefox Support Forum

At random, whenever use a search box on a page, Firefox will lock up. The "loading" icon on the tab will animate as normal, but the entire window won't respond. If I press the show desktop button and then try to reveal Firefox, none of the windows will appear. I'd have to go into Windows Task Manager and be lucky enough to terminate the correct process containing the tab, or else I'd have to start all over again.

When I load a page the first time, everything loads normally. Then if I refresh the page with CTRL-R, resources on the page (such as .js files) very often (seemingly 75% of the time) only partially load and therefore parse errors occur in the console. To reload a page, I have to hit CTRL-SHIFT-R to bypass cache and then the page loads normally again. I can also just launch the page in a private window (this loads properly), close the window and launch it again in another private window (this loads perfectly still) but it's becoming a chore to juggle with private windows only to reload a page I'm working on. I can see the resources loaded under the NETWORK tab in the console but they don't seem to be available to the page renderer or something.

Is this a bug in v100.0.2 or was I only having a bad weekend and all of this is just a random glitch that will go away soon? I've never had a problem like this with any previous Firefox releases (even v100.0) and I've used FF for approximately 15 years. It immediately began to happen after the v100.0.2 update!

What I have done so far:

- Exit out of Firefox and launch it again. - Rebooted the computer. - Site Information > Clear Cookies & Site Data - Waited 2 days for another FF release in case this was a bug and it rapidly got fixed (no update rolled out since). - Help > More Troubleshooting Information > Clear Startup Cache

Am I going crazy or?

I have seen this in some past versions of FF It usually goes away after a few upgrades

Instead of whatever it's supposed to display, you can see that it shows some random characters.

Annoying. I dont even remember what it's actually supposed to show

After i just updated Firefox to newest version .. I can not load any website anymore!!!!!! please make it so i can return to the previous version ASAP so everything works again.

When I open a website, the message "Firefox is already running" comes up every time. Task manager says nothing is currently running. I have to click "close Firefox every time I go to a website. Can you help? Thanks Alan Murray

This is my story. Digital affairs are serious problems for a marriage, although sometimes, they are also a symptom of underlying problems. Either way, you may quickly end up needing a divorce lawyer’s assistance if you do not put a fast halt to what is happening. Previously, traditional notions of infidelity required an actual physical relationship between an unfaithful spouse and their romantic partner. Thanks to the chxhack @gmailcom who helped me to dig into the communications of my husband platforms like his phone and social media, that i discovered that he was hacking extra affair and i got all the records of the communications and i was able to save my marriage. therefore if you are experiencing such worries get intouch with above. thank you.

The video's play fine, but when I click off the browser into another app, the video begins to lag and stutter.

I've tried to mess with the Performance settings to no avail - also disabled extensions with the same result.

When playing music on music.youtube.com, if I navigate away from the tab, by either moving to a different tab or opening a different application the music pauses. This happens consistently with two different Firefox profiles.

I admittedly have a quite a few plugins installed, so I tested this in a private window and this issue does not occur.

I attempted disabling the obvious plugins UBlock, 'I don't care about cookies', and Tampermonkey without any success. I also tried using a different user-agent without any success.

edit: removed erroneous error information

I've installed Firefox 105.0.3 on a machine with a fresh installation of Windows. I've left the machine running overnight. The next morning, Firefox stops loading pages. When I check C:\Program Files\Mozilla Firefox, I can see that Firefox.exe has a file date of July, instead of October: all the files in this folder are now for version 102 instead of 105. This has happened several times in a row now. What could be causing this problem?

I have Win 11 pro, Computer is new.

I believe after installing a windows update this week KB5018427, There is no sound on Firefox. (was working fine before).

Other browser like Chrome and Opera are fine.

I have cleared cache, reset firefox and the usual troubleshooting (including if the tab is on mute).

All sound drivers are up to date.

Can anyone help?

I am experiencing problems when using Duolingo, which is highly interactive.

This same problem was highlighted in Version 95.0.2 from a Windows user. The waveforms on System Monitor/ Resources are the same.

I am using Fedora and have 16GB ram. Have just ordered another 16GB ram, but think this problem is so severe that no amount of ram will fix it.

Unable to complete backup of firefox profile because of over-length file names in storage sub-directory. Is is ok to simply delete one or more file names which are old URL's and no longer required? Clear History All doesn't clean them out. (Firefox 101.0.1 (64-bit) on WIndows 10) thanks

I got mad at a website that wouldn't let me right click menu to save pictures, so I stubbornly saved them via less efficient means, in the process I picked up the Long Screenshot extension and this had an error shortly before or after I had an issue with Lightshot not appearing, other extensions did not appear either when I added them during this time period, but now these all appear with the exception of Lightshot, which gets deleted and reinstalled only to not appear, that of course being the problem, though I will also say that a right click menu not being there is like reaching onto my computer and pulling my finger away, sites that do that should be given the cold shoulder somehow, at least.

My picture-in-picture remains in full screen, even if I double click with my mouse. When I click the ESC button it just closes completely. I have restarted both Firefox and my computer, but I keep getting the same problem. Not just in YouTube either, also on other websites.

When I open gmail in Firefox browser, I lose the connection very often, it also happens with google drive. But it does not happen to me if I use Outlook from the web, I only lose the connection with Google from Firefox.

However, if I open the same thing using Google Chrome, this does not happen, it works correctly throughout the day, and I do not lose the connection.

My version of Firefox is 100.0.2 (64-bit) on my notebook I have Windows 10 Pro installed.

It periodically blinks and that breaks buttons that open menus and closes context menus from Firefox. Also disables some keys, the tested list is arrows, might need to test that on all. As it's version-independent, it might be a dependency issue. It also happens in safe mode, which is saddening.

Since the latest (5 May 2022) update to Firefox (to Firefox 100.0) my Gmail account does not work properly on my desktop running W11. Gmail frequently disconnects for varying periods, then reconnects, only to disconnect again almost immediately. Gmail will not let me open another account from within the current account. This does not happen on my Android phone where Gmail works properly. Neither does it happen when I run Gmail through Edge on my desktop. Hence I presume it results from an interaction between Firefox100.0 and Gmail. My wife has exactly the same problem using her Microsoft Surface Laptop under W10 since this latest update.

Well, I have applied all the options about proxy settings with the same result of long time for opening websites when first start of firefox. During these months I took notice to the one point, i.e. if I open website using firefox in the earlier morning there is no problem with the speed of opening as well as if I open another browser of edge the last one opens website without any delay. So the challenge of long time opening websites when the first start of firefox is still in force. How to resolve this?

Hello

I have just updated firefox 103.0 64bits on my pc windows 10. And bigs bugs : all web pages became huge zoomed at around 150 - 160% !

I managed to fix the huge zoom problem by installing this firefox extension : https://addons.mozilla.org/fr/firefox/addon/zoom-page-we/?utm_content=addons-manager-reviews-link&utm_medium=firefox-browser&utm_source=firefox-browser

and setting all web pages to 90% zoom with it. But this is not a solution because firefox has to fix this bug since this update! :(

And the toolbar has become much higher, which decreases my screen height, it was better before! :( See my screenshot where i circled in red the height of the toolbar which has become higher! :(

even the tab bar has become higher! :( i managed to reduce it a little in height thanks to a code that i inserted in the file userChrome.css ,but the result is not beautiful : the texts are too flush with the line ( see my screenshot where i circled in blue the tab bar that i reduced with code in userChrome.css )
