Firefox Forum di supporto

I use Firefox on Ubuntu 21.04 LTS and recently started facing delay of 3-4 seconds while trying to open any add-ons in top bar or even when trying to navigate application menu. I recently moved from windows to Ubuntu, no such lag or delay was there in windows.

What I tried- I tried to troubleshoot this problem with the help of troubleshooter present in Firefox and used the 'Refresh Firefox' option but still it was lagging too much. I also tried to remove all add-ons but still it was of no use. My system is fast enough to handle Firefox.

Hello please there's some about:crashes : The list is very long... There's some just crased today, thanks for your help.

Something strange happening with my Firefox for a few months, you can see the screens below. Letters disappear (but visible under selection or Ctrl+A), images are broken (but totally fine after being saved on PC), and all these acid green and pink parts make internet surfing a challenge. Refreshing pages doesn't help.

I tried deleting and reinstalling Firefox anew, without all plugins and stuff but the problem still was there. Cleaned the system with CCleaner, checked with ESET Internet Security. Google Chrome, Windows file explorer and all other programs are totally fine.

Please help!

This glitch happens since I've started using Firefox several years ago: every time I start Firefox it extends its vertical size by adding some pixels to its top and bottom.

How can I stop it? Restore xulstore.json each time I want to restore the FF window size doesn't look like a good idea.

Attached are screenshots of xulstore.json (colored is the current and black is the backup ones) to show the glitch clearly.

I'm currently using Windows 10 Pro.

Recently (a few days), I have noticed that math formulas are displayed as plain Latex code in a Moodle-based course viewed on my windows Firefox browser. There is no problem with other browsers and android devices. It seems to be related to the automatic update to the version 88 of the Firefox browser. Is any one else facing this problem? Does anybody know a solution?

Hi, when I watch different content in PIP mode at some point if I not with the source tab in focus the resolution or quality of the video in the PIP windows down bad, its is a little uncomfortable.

Hey, I have a custom build website, I do make changes consistently, But these changes aren't showing properly on firefox immediately. But on other browsers, these changes are shown immediately. Also the website few sections does not load well on this browser. I want to the website to load properly on every browser, as Mozilla has a good number of users too. here is my Yourdetail website link so if you can check if there is a problem there. Or is there any problem at my end

Firefox crashes whenever I go onto a certain web page such as a few parts of the discord website and some YouTube videos. I have tried nearly everything I can find which is somewhat similar to the issue I am having. I tried disabling WebGL, tweaking security.sandbox.content.level, reinstalling, checking my add-ons, and rebooting my macbook (macOS 10.13.6). The same thing happens on safari, but not chrome.

The crash reason stated is: EXC_BAD_ACCESS / KERN_INVALID_ADDRESS Here are the crash reports: bp-e8779820-e621-4739-a43e-e392a0210505 bp-29a6f662-0f4c-44d4-afbd-5e5900210505 bp-9ce6f8a8-6ddf-4771-824e-f94280210505

After migrating from Firefox 87 to 88.0.1 under linux-64 (debian 10), the browser became very slow. Typing has a delay of 2-3 seconds between end of type and appearence on screen. Same for loading pages. Migrating back to firefox 87 is a nuisance since part of the setup is lost and mozilla keeps insisting daily to switch to firefox 88. The articles in "Fix slowness" do not seem to help.

Any suggestion?

Today I had to screen share using google meet in an important project viva. I clicked on share entire screen on mozilla firefox in google meet and it crashed my system. It happened a lot of times due to which I have lost marks. Hate firefox switching to chrome :)

My Mozilla occasionally crashes on various websites but this is rarely a big deal and is usually restored without further problem. However, when trying to access my online banking (Co-operative and Smile) it crashes repeatedly after a few seconds, making these sites unusable. Anyone got any ideas why this specific site is a problem and how to overcome it?

My cookie cache is erased every time firefox closes and I only have Ecosia as an Add on. My security setting was strict but I changed it to standard. This had no effect. I'm not very familiar with Linux so a simple explanation would be appreciated!

Thanks in advance

P.S; The crash reports fail to submit. I don't know if this is related.

I'm unable to play Amazon prime video with Firefox version 78.9.0esr. It just pops out a message saying "Firefox is installing some additional add-ons. Please try again later".

For the last few versions of FF (currently on 88.0.1 (64-bit) OSX Big Sur) certain websites display text incorrectly where the text is bold and each character is offset with the next one (see attached Images).

It only seems to happen to certain websites and happens both within my web based email and on standard websites - but only some of them.

I've attached a photo of the issue in my webmail - I'm viewing an email sent to me using mailchimp, but even this is inconsistent as other emails using mailchimp are fine. And as I said before it happens on websites too (examples attached).

I have this issue on my 2020 iMac and my 2020 M1 MacBook Air but not on my 2019 iMac. All 3 are running latest version of FF and all synced to my FF account and have all the same settings. Attached photo of plugins/extensions installed too.

Please help me fix this it's so frustrating!

Thanks

YouTube does not work properly.

Before I start, I must mention that I have tried Chrome, Brave and Edge. None of the others have had this problem and I can confidently say that this only happens with Firefox and Firefox Nightly as well.

Something that I should also mention is I have security.enterprise_roots.enabled set to true in about:config. This is because when it's set to false, Any google related webpage shows a Potential Security Warning. I don't know if this has anything to do with the issue I am having with YouTube but I still wanted to mention it.

Finally, the problem - Firefox and Firefox Nightly both get stuck on loading whenever I click on anything on YouTube. Be it the Channel Icon to go to the channel or a video or even the search bar. Anything that should take me to the next page gets stuck. Screenshot is attached. The only way to open the video or the page is to reload it or to stop the loading enter the link and then manually do it every time I need to click on something in YouTube. I have reinstalled Firefox. Reset everything. Even reinstalled windows. But the issue persists. Any help is appreciated. Thanks

Problem: After this morning's update to 88.01 64-bit, magnet links do not work What I've tried: Found instructions online for resetting using about:config, but it's not working because the right click isn't bringing up the menu to allow me to create a new protocol and even after setting network.protocol-handler.expose.magnet to false, right clicking the magnet link doesn't let me choose a program. It just brings up the regular right-click windows menu. TIA for your help.

I rarely ask for help and try on my own and frequently help others, but I have a problem that I cannot solve and need your help, please.

I have tried the typical things such as restarting, starting in safe mode, refreshing, reinstalling, uninstall and delete folders and profiles then re-install, uninstall and delete folders and profiles and remove all Mozilla/FF entries in the registry then reinstall. No plugins or addons installed.

I tried disabling my anti-virus software.

I have FF version 87.0 64 bit version and even tried with an older 32 bit version. My OS is Windows 10 version 20H2 OS Build 19042.928. Both are the latest versions at the time of this post.

Regardless of what I try, my problem below persists:

When I start FF it almost starts but hangs. I can see it listed in the Task Manager. There is a little activity with Memory and CPU usage for a few seconds then no more. I cannot End Task if I try. It will hang like this for hours. Eventually I will get the home screen. If I attempt to visit a website right away it hangs (two dots blinking left & right like a school bus in the tab). If I do not try to visit a website but wait for a few more hours it will usually connect and be OK. However, if I open a new tab or Private Window I have the same problem in the new one.

Once it is up and running it appears to be working normally except for the new tabs. I have been hibernating my computer with FF open rather than shut down so that I can use it the next day. However, after a number of hours or on another day it will suddenly hang again for an unknown reason. Then I reboot and start the procedure all over.

I have tried every fix I can think of for FF. The problem may be an issue with Windows, but Microsoft has no bulletins or fixes for this one. I have updated to the latest build/version but nothing has changed. Very frustrating.

Any suggestions beyond the things I have already tried would be greatly appreciated. Thank you.

So I don't know what it is but FF hangs on startup. I mean the window loads but if I type something it isn't reflected. I also checked the task manager and clearly FF was hogging lot of RAM on startup (nearly 2 GB) and the fan speed was also increased drastically. I waited for some time so that what I typed was reflected on FF, clearly the RAM usage went down after 2-3 mins and the fan speed also decreased.

Another thing I noticed is that when the FF is the current window, Alt+tab doesn't work on Windows OS (the windows don't switch). I tried with another applications as the current window and Alt+Tab was working. I don't know why.

I saw this changes after upgrading FF to the latest version (88.0.1 (64-bit)). I think these are the bugs in the latest version.

Someone please rectify and patch the bugs. Thank you.

Firefox has been constantly crashing the last few days. Sometimes the tab crashes but the window remains open, sometimes the entire window crashes. I followed the steps on the troubleshoot page (except for checking RAM errors) but everything is up to date. The browser also crashes when starting up Safe Mode. Here's the Report ID: bp-bf163db4-86a7-47ff-9804-215f30210508

I've been a long time Firefox user since around 2005 and have always enjoyed Firefox until now. This issue has been ongoing for over a year though. I never would have thought that a simple task as entering a web address in the address bar and hitting enter would become so difficult, though for a while now this seems to be the case and to the point to where I'm considering not bothering with the Firefox browser anymore. I do enjoy where Firefox is now in current development and the way it looks as well the great performance. However, when basic functionality such as typing in a web address and hitting enter becomes difficult all the aforementioned positives become less and less relevant. It seemed to all start when development came to redesign the appearance of the UI, not sure what version. Basically, what I come to experience now roughly 90 percent of the time I type a web address in the address bar and hit enter is the browser does nothing. Sometimes it takes 5 to 6 tries with having to put the mouse courser back into the address bar and hitting enter multiple times before the browser decides it want's to go the website. Same issue occurs when opening a bookmark in another tab, switch to the tab and the site isn't loaded, have to hit enter multiple times before the web address will begin to load. Seems also that any setting regarding tabs background loading isn't present anymore in the settings either. Same issue will occur when selecting a favorite that comes up while typing in the address bar.

Recently I had reinstalled my entire operating system and was hopeful that this issue would be resolved by doing so with a fresh install of Firefox too, though the issue is still present.

I have no add-ons or themes that modify the address bar, nor any search add-ons. In fact, this issue occurs with no add-ons installed at all. The only thing I can think currently is that it is an issue and or bug of some kind within the search and or address bar settings current design.

My settings here are attached as images.

I would like to inspect the rendered HTML elements in the iframes, at sites like codepen, codesandbox.

However, the iframe context selector button doesn't show up. Its also greyed out in the dev tools settings, and as visible in the image, I have the required option enabled.

This feature works as intended, in the default versions of Firefox. Tried Firefox Beta version 89.0b9.

I am on Windows 10, using Firefox Developer Edition version 89.0b9.
