Starting 2 or 3 days ago, Firefox began displaying PDFs incorrectly. The problem is that a single letter is omitted here and there. In the attached screenshots, the first one shows the word. "Department" with amissing letter "t" in the middle. After refreshing the screen, the PDF displays correctly, as shown in the second screenshot.

This is occurring on a Mac; it does not seem to occur on a Windows desktop machine.

I am running Firefox Desktop 155.1 on MacOS Monterey 12.7.6.

Hello! My Firefox browser is currently in a state where all fonts/letters in the Firefox interface (bookmark bar, settings, about page, website name...) are replaced by undecipherable characters.

I've searched for similar problems already and tried so far the following steps to resolve, unsuccesfully...

• Opening the browser in Safe Mode / Deactivating all extensions
• Uninstalling and reinstalling Firefox

• Disabling hardware acceleration
• Trying on another profile




When I copy paste said text to another window (ex: Notepad, Chrome Browser…) it appears properly. And as you can see in the screenshots below the text in actual websites is readable -- only the browser's interface, setting, address bar... are scrambled.

Does that bug rings any bell? Do you have any other troubleshooting steps I should try to resolve this? Any help will be appreciated! : )

Sometime in the last week or two, every page starts with a banner that says "you must sign in to the internet to continue". I'm already/always signed in. On those few occasions when I click on the network login link (rather than clicking X to dismiss this dangerous and wrong banner), it shows a very dangerous site and says that site is prohibited. (As it should be.) So why is the banner demanding that I log in (forcing me to click X to dismiss it)? This feels like your site has been compromised, that some malicious actor is forcing this prompt on every page. (And even after I click X to dismiss it, it reappears 10-15 minutes later.

how do I get rid of these annoying webpages that appear automatically when Firefox or it's adblocker has updated? it's like advertising for an app I already use the whole time.

thank you, blue

Good evening, the built-in VPN has not been working for a week, when enabled, NO sites open and the message "could not connect to the VPN" pops up, the browser is blocked completely, what to do?

I moved bookmarks from old mac to new mac so I can visit all my websites. However no user names and passwords load on the new mac. I hit sync over and over and nothing happens. Thx in advance for your help.

For the past month, out of the blue, I have been unable to play Spotify via my web browser. After troubleshooting with Spotify chat, it seems the issue is actually Firefox, because if I choose to play it via the app installed on my computer, it will play, but not via the web browser.

It was display "Spotify can't play this right now".. then it will skip through three songs, play ads & then will play the first 10 seconds of audio of the next song & then it will cut out.

Anyone else experiencing issues with Spotify via the Firebox web browser?

I'm getting popup ads that open a new page after I punch a link I hit the link and an unrelated page comes up inn addition to the link I intended to open. It even does that when I click on an email. Is there a way for me to stop this? This was happening before I upgraded to the version I'm on now.

Facebook pages will not load. I need specific detailed instructions how to do this. Dyslexia makes it difficult to process written directions. I want to disable adblockers and other extensions to allow Facebook to load pages.

When I first start up Firefox this populates the address box http://search.anysearchmanager.com/?hsypt=iima&pub_id=3000&affid=A0X7K_set_bfr_H. this is also accompanied with a warning that this is a possibly compromised site. If it is a bad site why does it show up when I open Firefox? HOw do I make it go away?

Running 154.0.1 on MacOS 26.6.1. Sometimes firefox stops working and I think I'm having an internet issue. No page able to load, not even a google search. I see the cache is full at 1gb and I clear cache for the last hour. Browser starts working again. To me, the problem doesn't seem like not enough cache capacity but the browser refusing to evict old, stale cache. How do I fix this other than manually clearing the cache? This seems like a bug that should be fixed.

My VPN has. stopped working although it has reset as it does monthly, worked fine a week ago, Still have 50 gig and won't engage with server? any help appreciated....
