Firefox Support Forum

Hi all,

Had my text font changed all of a sudden. I'm not sure if I've accidentally pressed a shortcut to change any setting.

Image attached also show that this change has caused some misaligned numbers on a browser.

Is there a way to revert text to my previous settings?

Hello,

For two firefox updates, I've been having an issue where after about an hour or two of using firefox (it varies), video players on most websites will stop working. Almost every website except for Youtube's videoplayer stops working after an hour, all at once. Restarting firefox fixes it, but it's very annoying to restart firefox every couple of hours, and seems like a problem.

The following things didn't fix it: clearing my cache, disabling my addons one by one, turning off hardware acceleration, trying to watch the video in a private window, or reinstalling firefox. I don't know what's left to try. It has nothing to do with my audio devices.

Please advise, thank you!

Instantly upon installing the latest update I've witnessed glaring issues across the board with Firefox that are severely impacting my ability to browse websites.

The two major issues are as listed in the title, all text is about 10-20% smaller, the ui elements displayed within web pages are also shrunk to this same degree (zooming in the page just makes everything appear distorted and thus is not an acceptable fix), and many parts of text or coding are broken on pages that cause them to display the wrong colors which make many sites all but impossible to read.

I do not utilize any of the windows settings for zooming or making text larger, I've already attempted to clear cache and cookies, and thus far I can't find any way to resolve the issue. To be clear, this is a firefox issue because other browsers such as chrome still display everything perfectly.

I didn't change or adjust anything, but when I opened Firefox this morning some websites are displaying differently. On some websites, the font size is smaller than 'normal' (see attached Wikipedia screenshots), some font styles have been changed (see attached Serebii and Archive of Our Own screenshots), and some websites are not displaying properly (see attached tumblr screenshots). I have cleared my cookies, cleared my browsing history, reset my browsing and font preferences, disabled all of my add-ons,disconnected from my VPN, logged out and back into Firefox, restarted my computer, and uninstalled and reinstalled Firefox, but the issue still persists.

I'm aware I can custom adjust the font size, which solves the sizing issue, but not the display or changed font.

I've included screenshots of the issues, as well as Chrome screenshots for comparison.

Is there anything else I can do to fix this? Thank you for the help!!

Although I had long ago selected "Open Previous Windows and Tabs" in Start-Up, my windows and tabs were not restored when I inadvertently quit Firefox this morning and restarted. I then went to the three horizontal bar Application Menu > History to look for "restore previous session", but that button was missing.

So I have two questions: 1. Why didn't my selected preference, "open Previous Windows and Tabs " at Start-Up work? Is there a fix? 2. What has happened to my "restore previous session button in the History tab of the Application Menu, upper right of toolbar? Has Firefox deleted the "restore previous session" button? Can I reinstall it in some way?

I'll be grateful for advice. Thank you

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?

The issue appeared about two days ago. On the page https://index.hu/ the left click is not working from firefox. This is the most popular news site in Hungary. I also experienced the issue on other sites.

It is working fine from chrome and chromium. The issue is appeared on linux and windows 10 machines as well.

I tried to clear the cache but it does not help.

Please fix this ASAP or I have to delete your browser.

Frequently when I update Firefox something stops working the way I want it to. So after the last update I disabled updates. That was a while ago (version 89) and my browser was getting pretty stale. So I backed everything up, reenabled updates, and now I have version 104.

And, of course, something is broken now. The context menus when I right click are not functioning as before. The userChrome.css is still there in the chrome folder in my profile and has the same contents. The option toolkit.legacyUserProfileCustomizations.stylesheets is set to true. But it doesn't work anymore. I added a line to change the color of the tab toolbar and that worked. So userChrome.css is being read and acted upon. But the other command (I whittled it down to just one additional command for testing) is ignored.

Here is what my userChrome.css looks like right now:

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

1. context-openlinkintab { display:none!important; }
2. TabsToolbar{ background-color: #CCCCCC !important }

But the "Open Link in New Tab" still appears in the context menu when I right click a link. It didn't do this before the upgrade to 104. Did something break in between version 89 and 104 or is it some other oddity?

Any ideas?

I just upgraded to a 4k monitor and the blinking cursor is so thin I can not see it. I have adjusted the thickness in windows 10 with took care of the issue with Microsoft applications but I can't figure out how to make it thicker in Firefox.

I've tried changing from Firefox theme to System theme but there was no change. Fonts is set to Segoe UI 17.

I have System theme -- auto enabled.

Any suggestions?

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.

When playing videos, specifically on YouTube, I can see some blocky/pixelated sections in video playback.

Issue is not present on Chromium-based browsers, I've tested in Vivaldi and Chrome. Both are using dav1d.

When AV1 is disabled through "about:config" the issue is gone, but then I face a stuttering problem.

This are my laptop's specs:

My new Windows 11 laptop forces me to use the "Mail" app to forward links by email using the "email a link to this page" utility feature in the Firefox toolbar Prior to this, my old laptop would just use Outlook which was quicker/better.

The multi-step method using Mail was cumbersome so in trying to designate Outlook as the sending vehicle over Mail, I designated a non-performing solution which is now preventing me from emailing links (and captured webpage info) at all. I would like to migrate back to Mail or find the correct choice for Outlook but the "email a link to this page" in the Firefox toolbar does not work now as a result of my poor choice.

Anyone know how to fix this? I have "restored factory defaults" and other on the toolbar features but does not help. This was apparently an unrevocable choice.

Hello, I've upgraded my Ubuntu distribution from Ubuntu 20.04 to 22.04 yesterday. This forced me to update my Firefox version, I am now running the 104.0.2. I now have the following issue: on some websites, the page loads normally but as soon as it's loaded, the page becomes entirely blank. This doesn't seem to be a website issue, as it actually appears normal for a very short instant before it disappears. A website for which this happens is: https://www.lalibre.be/ (I only encountered the issue on another website but it's from the same editor). I tried in a private window and it works normally! I tried in the normal window after deactivating all the addons, it still doesn't work. I tried with or without the Firefox account logged in, it doesn't work. Until now, it's only these 2 websites from the same editor, but as I said, they worked fine yesterday, they work fine on other browsers and they work fine in Firefox private mode. Any idea where this might come from?

Trying to open any link from a pdf opens a page with the url resource://pdf.js/web/ instead of opening the link. The attached image shows what the page that opens looks like. This does not happen on Edge, so it is a Firefox issue.

I have updated to the newest Firefox version and the issue remained the same. I tried clicking on "viewer.html" and it brought me to an empty pdf page that just loads forever and cannot be downloaded.

Please help. I do not want to use Edge or go back to Chrome, but I will if this can't be resolved.

Firefox update required me to restart Firefox. I was unable to save a bunch of work I had done in a particular tab because Firefox seems to have refused to connect to the site I was working at until I update. THAT SUCKS!

Hello Is it possible to use the stylus add-on to remove the stories from Facebook? I am not a programmer by any mean but i like to "play" with the inspector and i found out that by deleting a node the stories disappear. So I was wondering if i can use stylus to delete this node for me! Thank you!

I am not able to download any kind of file, from any kind of website to my disk. I am able to select open on the download dialog, and this will open the file and save it to the temp directory firefox uses for this function, but this does not save the files to disk/the download folder like I want to. I am unable to "Save image as..." as well, since this is considered a download. There is no record of these downloads even being attempted in the download history.

Hello All, I recently had to start up my brand new MacBook Pro up in "Safe Mode" to verify an unrelated problem. When I restarted my computer from safe mode, my Bookmarks were either gone completely or "empty" and I was apparently in a newer version of Firefox. I then trashed my Firefox application and tried to restore an older version via Time Machine and after I copy it to my Applications folder I get the message that I am trying to open an older version of firefox and then doesn't allow me to do that. When I followed the option to their extents, only the new version with NO bookmarks shows up.

How can I get my old bookmarks back?

Thanks bc

My FireFox media player was working fine this morning. Now it will not play the mp3 files I need to play for my work. Also, there's no sound on YouTube when I use FireFox. I have system sounds on my computer, and I have sounds on Google Chrome, but there are no sounds on FireFox. The media player will open with the mp3 files, but it does not move or play at all. I disabled my antivirus and it still won't work. So that is now fully back on. I uninstalled and reinstalled, restarted my computer, I have done so many things over the last 4 hours and nothing is working. There was a Windows update today that happened shortly before this problem occurred.
