Today, I noticed that fonts on sites look different than normal. At first I noticed that font looked smaller, but zoom is set to actual size. Then I noticed that while on a site with a black background the text was displaying as black also, making it impossible to read. I looked through the preferences and everything pertaining to fonts and colors appears to still be set to default. Next thing I tried was opening the same site in private window. While in the private window, the font and color appears as it should.

Any ideas how to fix this?

All of a sudden, after waking my computer from sleep, I found that many websites in Firefox are displaying the main text content at 13px, ignoring font sizes specified in CSS etc. I first discovered this on my organization's website, I thought it was a browser cache issue, but it has persisted. The text content on our front page is all the correct size, but everything on the website that is "main content" text that is not in a heading tag, like blog post or regular page content, is rendered at 13px. Other sites like Wikipedia load this way as well. In private mode, the issue disappears. In Chrome, the issue does not occur.

I have cleared all cookies, browser cache, site data, history, and the problem persists. I have checked the default font settings in Firefox, the checkbox saying websites should override the font settings is already checked. Zoom is set to 100%. I updated to the latest version in the course of restarting, and it didn't fix the issue either.

In the attached screenshot, the examples on the left are in regular Firefox windows. On the top right, a page on our site is displayed correctly in Firefox private mode. In the bottom right, Wikipedia is displayed correctly in Google Chrome.

Every time I try to use the search function I get this message, saying that they can't find the URL. I've already tried checking my connection, my firewall, restarting my computer, using the troubleshoot mode, and uninstalling + reinstalling again. Can somebody please help?

Greetings:

First experienced: Friday, Sept 2, when using burpsuite/foxyproxy during a hackerone CTF.

When using other Vbox instances on the same computer I have the same issue. This issue is usually easy to duplicate when using dev-tools or by simply doing an image search and moving the mouse across the images.

Host: Ubuntu 22.04.1 LTS 5.15.0-47-generic #51-Ubuntu SMP Two different VGA controllers are present: Intel CometLake-S GT2 AMD/ATI Ellesmere Radeon RX

VirtualBox: 6.1.34_Ubuntu r150636 (Qt5.15.3) VirtualBox VGA: VMware SVGA II Adapter

Guest: Kali 2022.3 rolling 5.18.0-kali5-amd64 #1 SMP PREEMPT_DYNAMIC Debian 5.18.5-1kali6

Crashes have seem to involve input from the mouse and scroll function within the browser. Once, let us call it a glitch, the crash can either take place while continually moving the mouse around the browser's page or immediately outside the page with the mouse. The "glitch" is a coloration, usually pink or lime-green with characters printed to screen and then disappears. I have been unable to predict when the glitch will happen, thus no screenshot to help.

Steps I have taken:

Googled on the problem which led me to learn about the Firefox about:crashes function.

Viewed about:crashes -- seems to be a Renderer issue linked to llvmpipe or Mesa?

Checked basic system logs for host and guest for anything evident: syslog, kern, Xorg, messages, dmesg, daemon, journalctl.

Used Firefox troubleshooting and extended troubleshooting.

Installed Firefox 104 with same issue.

Reinstalled VirtualBox.

Search on Firefox Renderer issue [from crash report]

     I turned off performance settings, still have same crash issue.

Last Report ID that did not fail to upload: bp-740acc47-0ed4-44a8-851c-ff21b0220905

Ultimately, I am unsure if this is a Firefox, VirtualBox, or Kali Linux issue, but Firefox is the one that this issue is having a severe impact on. My head is spinning at this moment due to all the logs and information I have digested over the weekend.

I appreciate any efforts in helping me decipher what is going on!

Respectfully,

Steve

I upgraded to Ubuntu 22.04 recently. Since then Firefox 104.0.2 (64-bit) has been arbitrarily freezing; sometimes i have to restart the computer while most of the times I am able to kill the Firefox main process and restart Firefox.

The freeze occurs when i try to save a Web page; i don't see any "logic" as to which Web pages cause Firefox to freeze. It seems totally arbitrary.

I clear my downloads list everyday (sometimes more frequently than that) and clear cookies & cache everyday.

I have selected "no proxy" by default, in 'Connection Settings'.

This never happened until after i upgraded to Ubuntu 22.04.

I've browsed the support pages and don't find anything relevant to my problem. If I'm overlooking something, I apologize in advance!

I have attached a 'screen capture' image of Firefox processes just before i killed the main process.

Thanks in advance for any suggestions. Ramki

When typing comments on a web blog, after the spacebar is used, the first letter of the next word eliminates the previously typed space. So what I end up with is all words in a sentence running together. Tried other browsers and they work fine. Changed keyboard as well no joy. Typing is normal in applications like adobe, word, etc..... Only happens during Firefox use......... Uninstalled and reinstalled Firefox, also no help..... How do I fix ?

Hello! After updating to the latest version of Firefox (100.0.2, 64-bit), I notice that Google search stops working every now and then. By stops working, I mean I can't use their website https://www.google.com or search using Firefox's address bar or search bar. Searching with other search engines like Bing is working normally. In order to get Google search working again, I have to close and restart Firefox. However, after some time, it stops working again. How can I fix this problem?

I can play videos and audios on another browser or files stored on my computer, but just now I cannot on Firefox. I saw the FAQ explanation about Windows 7, but I have been using Firefox for years including just hours ago using Windows 7. Why would this happen right now? Did some new version just get installed? If so, can I return to the prior version and turn off the automatic update?

Thanks, Phil

The mouse-left click button does not work since last two updates!

The link is OK, floating menu with right click can open it in new tab, but left-click on buttons, divs, links is dead for a while

Something was changed in Firefox in the wrong direction.

Please help

Since version 98, Firefox still saves files in the designated Downloads folder, even if I just want to open them. This new behavior keeps cluttering up the Downloads folder with unnecessary garbage. What I want to have in there is what I choose to download myself, not some temporary files. That's what the Temp folder is for.

The problem https://support.mozilla.org/en-US/questions/1370409 is marked as closed, unfortunately with no fix. Will anyone be addressing this yet, or do users have to get used to it?

I, after a few months, chose to switch back to version 97.0.2 I will no longer accept updates regardless of new security patches. Unfortunately.

I use a laptop with Fedora 36 installed. Firefox is version 104.0.1

Until a few days ago, there were no problems with video display. But since a few days, video content that is offered by the news site from NOS (Dutch television) is not displayed anymore. I only get this error: The media playback was aborted due to a corruption problem or because the media used features your browser did not support.

Also some content on Youtube aborts. For example loading https://www.youtube.com/watch?v=qq0BUiEs3JM results in this error: Er is een fout opgetreden. Probeer het later opnieuw. (Afspeel-ID: Ui0fzPxdSexgYcZ4).' (An error occured, try later again).

When using the Chrome Browser both websites can be used without giving errors implying that all the codecs are available.

How can I detect why video is blocked?

(Twitter also gives problems. After a fraction of a second, it stops displaying video)

Hi, so yesterday, I updated to the latest version of FireFox (version 105.0). Nothing seemed to be out of the ordinary until I decided to watch a few YouTube videos. The best way I can describe this problem is that every time I decide to scroll down to see the description or read a few comments, the entire screen on my laptop goes black regardless if it's on default view or full screen.

Even though that does sound like a crash, the audio still plays, and if I power the computer to sleep mode and log back in, the window of the video automatically scrolls up and everything is back to the way it was (but I did had to restart the laptop once because it also visually broke my mouse pointer). The only way I can get around this problem is to pause whatever video I watch and then scroll down, and no black screen occurs.

I don't know if I'm the only one who has this problem, but I've never had this issue happen in past versions of FireFox. If there is another way to fix this problem, I'll be glad to take anyone's possible suggestions/solutions.

When I click on an article or any link in Outlook, I get an error message that says, Your organization's policies are preventing us from completing this action for you. For more info, please contact your help desk. I'm not an 'organization', just a user and obviously there's no help desk to contact, so I thought I'd reach out to see if someone might have a solution to this problem. I have already made sure that my default programs are set to Firefox for my browser and Outlook for my email and made sure all the defaults are selected. I have also run a full windows scan program which came up without any errors and I have run a registry scan that fixed every identified error. I'm still getting the same error message and the only way for me to open up an article or a link from an email is to 'copy hyperlink', open up a new tab in Firefox and select Paste and Go, which is driving me nuts and wasting a ton of time. I don't know what else to do at this point. I did find a document on the internet that has what it says is a method to resolve this exact error message problem, but the instructions are specific to Internet Explorer, not Firefox. I'm hesitant to find those same tools on Firefox (which is quite possible, though some of them are in different places on Firefox than they are on Internet Explorer). My concern comes with the fact that the final step will 'reset' every setting to it's default condition, so it seemed like a good idea to try to get some expert help before I perform such a drastic action. Also, I'm also making the assumption that if I did do a complete reset, I would be able to restore Firefox back via my most recent System Restore and it would bring back all my customizations, browers add-ons, personal settings, home pages history, cookies, privacy settings, etc. - but I'd like someone to weigh in on this. Thanks for any help anyone can provide.

Hello, I need help, it is not possible to open Firefox. After opening, the window closes itself again, a new profile was created, but the problem is still there. I am very unhappy about this. I didn't load a new extension, didn't use new antivirus software. Firefox has already been uninstalled and reinstalled. The problem is not solved. I've also cleaned Firefox a few times, but the problem still persists. There are no crash reports as Firefox just closes and doesn't crash. I can start safe mode. I am sending the Troubleshooting information.

Thanks for your help, Firefox is the best browser! Greetings Silke

I'm on Ubuntu 22.04 which is using the snap package of Firefox.

It seems that I cannot open local files in the /tmp directory. When I place a test.html file there and run `firefox /tmp/test.html`, it returns a file not found error. Why?

I don't have the problem with files in my home directory.

Dear Community,

I've been struggling with a very peculiar error with my Firefox in the last couple of weeks that I haven't managed to find a solution for. It's kinda disturbing and makes me want to stop using the whole thing, even though I'm a big fan of Firefox.

1.) The first sign of the error is the browser suddenly becoming partially unresponsive. The UI still works - as in, you can scroll down/up on open pages, navigate through menus, open/close tabs, etc. but no HTML content is loaded JS isn't running. First I thought this was just bad connection, but I had a stable internet connection and other browsers would load the same pages. 2.) At this point, when I try to close the whole app and restart it, I get a message that the browser is already running. The dialogue box also offers to force restart the app, which doesn't work (it stops the process but doesn't restart it, so I still have to manually launch the app). 3.) After manually launching after failed force restart, I'm getting another error message saying that I'm using an "old version of Firefox", due to which my old profile "might not work". I can either exit the app or create a new profile. From a new profile I can load profile manager but I'm unable to launch the other profile. However, indeed there is an app update pending. 4.) After the update is installed, the browser launches the new profile and and then from the profile manager I'm able to load the other profile, set is up as standard and remove all other profiles. After this step, all seems to be normal and Firefox keeps working without any issues until a next update is found, but then the whole issue starts from point 1.

First time I suspected that the profile is corrupted, so I deleted it and resynced the settings from my Firefox Account, but this has not helped, so I fully removed Firefox with all the data stored on the local drives and reinstalled it. Then the latest version was installed and the profile worked, so I presumed the issue to be resolved until a new update came. In the last month there's been at least 3-4 updates, all triggering this very peculiar issue issue. I was thinking this might be known so the devs would release a fix soon, but I couldn't find the same issue mentioned, so now I'm suspecting one of the add-ons acting up. However, since the issue only reproducible when an update is released, it would somewhat complicated and time-consuming to deduct which one is causing the error. Hence, asking question here as I'm wondering if anyone had encountered anything similar or could suggest any further steps to fix the error.

I'm using 104.0.2 (64-bit) and following add-ons:

I haven't captured the exact error messages but I'm happy to do if that sheds some further light on the issue (would have to wait until next update for the issue to happen though). Any tips would be appreciated.

Hi all

I'm a happy user of FF but have started to see issues with JavaScript (error message: You need to enable JavaScript to run this app.). I do the about:config correction and it sometimes works, but now the error is spreading to involve other pages - a page worked yesterday doesn't work today.

Is it just me?
