My font on some sites is being forced to this horrible condensed font and it's seemingly nothing to do with my font settings in browser. Thing is, I VAGUELY remember changing a setting SOMEWHERE to actually do this, but it's not the main font setting in accessibility. Furthermore this issue has only started happening in the last day or two and my vague memory of setting my font somewhere was years ago.

Is there any other setting in Firefox that affects default font for certain sites?

Hello,

My Win 11 Home (ver 25H2, OS build 26200.9168) Dell laptop runs Firefox v. 155.0 and doesn't load costco.ca however my iPhone 15 Pro Max running Firefox v. 154.1 does. The laptop's browser initially loads the costco.ca landing page (for 1 second) then displays a white screen with this message: "Application error: a client-side exception has occurred (see the browser console for more information)."

What can I do to enable Firefox to load Costco.ca on my laptop?

Thanks,

Steve

I'm encountering some UI errors with the last couple updates. With an update from a couple weeks ago, I noticed when viewing PDFs in the browser, random characters would be invisible, and in Google Sheets I'd notice some cells appeared blank, though selecting them showed that there was text inside. I also noticed disappearing text in a Google Doc I was working on. Now with the update that was just released today (154.0) all PDFs, and entire screens in Sheets and Docs, and other random graphic elements, are showing up as just flat black (see attached screenshot). My job involves working with spreadsheets and PDFs a lot so this is severely impacting my workflow, and I am reluctantly working in a different browser today.

I did a browser refresh, and then I uninstalled and re-installed, and that didn't help anything. What should I try next?

I should note I am using Firefox on Windows 11. I am not experiencing any issues with Firefox on iOS or Mac OS.

Edit: I was able to troubleshoot and fix this by disabling hardware acceleration under performance settings. Problem solved!

I have had a bit of a problem with a keyboard today and tried downloading drivers and reading faqs about it, and apparently as of today (august 20th 2026) firefox decided that most sites are unreachable (which they clearly are since the laptop running win11 works) Why the sudden overstep? BTW I can't access this page on the win10 computer.

images, text boxes dropdown menus and anything of the like reload the moment i scroll even slightly text boxes and dropdown menus dont reload text or option chosen just the image/ box no clue what could be causing it doesn't appear on mobile just PC. appears when searching with duck duck go and google also reloads when moving over images and a good chunk of the time only loads them partially/ flickering, not unusable just annoying thanks

I use Firefox trying to access myGov account. I can Log into myGov account without any issues, but once I log in. I can't click on link within myGov to go to any of the linked services. Forefox just stay on the page without going anywhere. Every time I want to log into MyGov, I got to use other browser like Microsoft Edge. In Edge or Chrome, the same log in process, but then when I click on the linked service, like ATO, Medicare, etc. It actually take me to ATO, or Medicare etc, where In Firefox it does not work when I click on the link.

Firefox 152.0.3 on Windows 10. SVG icons such as Google Maps interstate shields flash briefly then turn into squiggly lines. Same issue occurs when uploading images to websites and viewing Amazon book previews. Works fine in Chrome. Already tried: disabling hardware acceleration, toggling gfx.webrender.all, gfx.webrender.software.d3d11, gfx.webrender.allow-partial-present-buffer-age in about:config, clearing startup cache, removing Tampermonkey extension, disabling Killer Network Manager (CNMNSST.exe). I uploaded an image of how interstate icons show up in google maps.

I started using Firefox because I was having issues with cliches in my banking app with Google. And I don't like using google. My grand daughter recommend Firefox.

I have Windows 11 on my laptop and downloaded Firefox for Windows 11. Everything worked great for a while, then I started having the same cliches with Firefox that I was having with Google. The bank IT tech support advised me to clean my cache. So I did and everything was fine,,,,, for a few weeks and now it has done it again. This caused me to go back and clean my cache again, I did that, restarted my banking app and now it is working fine.

The most confusing part is. when it cliched this time. I went in to verify my Firefox version and my Windows version . The best I could tell, my windows is 11 but my Firefox in 10, so I don't know what I'm doing. Why would is show that when I downloaded the version 11?

Finally, am I going to have to clean my cache on a regular basis or is there some way I can have it cleaned automatically by my computer?

I am 70 years old and I have worked on my own computer since they first came out with home computers with dial up modems with out windows, We had to use DOS commands,.. So I use to know my way around computers pretty darn well.. Now technology is so advanced it is like Greek to me. I need some easy instructions and a K.I.S.S. (Keep It Simple Silly). So can and will someone talk plan English to me?

Thank you for any assistance you can give

Firefox is up to date, Windows 11.

I frequently watch BBC videos but approx one week ago, they stopped playing. I have your VPN which is usually off as it give me no advantage, (this appeared following the last update), but I've tried switching on and changing to UK location. No change.

Can you give me some suggestions please?

I chose passwords and sign in, but there's more. You are already aware of the Facebook issues but there are others issues with this and I personally don't have time to tell you how to do your job. I have to keep up my production to keep my job. Your browser really cost me labor time. So, I would like to know do you recommend going back to a previous version until you fix this mess? OR... what ohter browser would you recommend as your replacement?

I appreciate your time, and I look forward to your answer.

Thank you R

Hello, I can't log in to Facebook, only through Firefox, and that's the problem. Edge and Chrome work fine. I've already deleted cookies and temporary files, and still nothing. This problem has been occurring for a while.

no sure if this is the right topic place, but nothing else seemed any closer. can anyone tell me what the h*** the error message i keep getting when i do something like "sort by unread" and then go back to "sort by all"? i also have trouble just logging in - i have 3 profiles that i use. could not find anything in the troubleshooting section and i don't think it would be from the malware app as everything worked just fine for several years with this running any help would be greatly appreciated! wolfgang

I have just started getting Virus/Trogan messages from McAfee when brousing with Firefox. I have not installed McAfee so is this a blackmailing/SCAM by McAfee to get me to pay?. I only get these messages when using Firefox, It seems to be somthing that's got into Firefox! I don't, at the moment, have this annoyance on my Laptop.
