Every time I try to view a pdf file on Firefox I can view the file but in the lower right 1/4 of the screen I get a graphic of a page with shaded areas representing lines with writing on them. There is a type of pen cursor moving along the line.

This happens with different pdfs - from the internet and from my saved files. This doesn't happen on another computer with Firefox.

I've deleted and redownloaded Firefox an number of times, also tried troubleshoot mode - no improvement. Virus scanned, restarted a number of times.

Pdfs work on edge and chrome and reader with no problem.

I have a screenshot.

Any Ideas? Thanks

Hello, I'm having a problem with the NordPass Firefox browser extension. I have already troubleshot this issue with NordPass and they are passing it off as a Firefox problem.

Issue: When logging into the NordPass browser extension, my username and password are accepted, then Cloudflare does a human verification, then the extension throws error 1004 (Something went wrong) [screenshot of error attached].

Troubleshooting: - Tried updating Firefox to latest version - Tried clearing cache/cookies - Tried uninstalling/reinstalling browser extension - Tried uninstalling/reinstalling firefox

Additional: - Dell Optiplex 7090 running Windows 10 Pro - Issue is specific to this computer only - Extension was working as recently as 2 weeks ago - Currently, NordPass allows me to sign in successfully on my phone, in Chrome browser extension on affected computer, and in Firefox browser extension on different computer.

Latest answer from NordPass team: [Please note that our developers have investigated provided logs and traces, however, there is nothing wrong with the backend flow - it looks like there is an issue with localStorage or cookies as the NordPass extension is not able to fetch properly the token obtained from NordAccount login flow. As this is not reproducible on other platforms and traces do not show anything else, we can only suggest the verification of extension/firefox browser configuration, especially in terms of cookies, local storage and session.]

Any suggestions on root cause, or settings changes to fix this issue are appreciated.

For the past few weeks Firefox has been crashing and freezing often. Crashes are worst when trying to access Protonmail, which almost always crashes the tab instantly. Freezes happen most often when browsing Reddit, and also when watching Youtube, but crashes and freezes can happen on almost any website.

I have tried changing profiles, refreshing and uninstalling/reinstalling, but the problem persists and seems to be getting worse over time.

Here are some recent crash reports:

Will be grateful if someone can help me get to the bottom of this Thanks

I used to play World of Tank and look at YouTube on my second screen. Everything went smooth untill this week. YouTube on Firefox on my second screen is lagging or freezing. I tried Opera, I tried Edge it worked fine, but with Firefox, it is no more possible to play YouTube on my second screen while playing. It is not a matter of graphic hardware as this issue only happen with Firefox. I tried to deactivate every module and to reinstall Firefox (either the Beta version) but still got the same lagging and freeze on YouTube. Do you need anything that can help you to investigate this issue, this is really terribly frustrating and boring.

I just installed the MozillaVPN extension on my Windows10 laptop but can't use it because when I select the tool, it tells me to download and install Mozilla VPN - which is already running ! I've tried closing and re-strarting Firefox, and stopping & starting the VPN manually, but that doesn't make any difference.

Avast reports that it has secured the threat of 'addons.mysafe-search.net' which tries to start when i open Firefox. I've been unable to find any reference to the site anywhere on my PC so cannot uninstall it.

I have been block since yesterday afternoon on Mozilla to use this Etsy.com. I have reset history and cache per Etsy and it would work once after signing on and then it would block me. Now I have to use Chrome to get access to my account. I need to have this break in service fix for Mozilla/Firefox. Privacy and security is important to me. Thanks

does Firefox no longer support sites like The Guardian, like the Atlantic, other news outlets. it never lets me sign in but returns to the home page after signing in with email and password. What do I do?

new install of firefox won't load accounts.firefox.com

other browsers on the computer load it fine

I've imported bookmarks and passwords and stuff, and since refreshed firefox but can't find a way to fully restore it to initial settings, even uninstall and reinstall won't do it

google search said this is Firefox intertnet speedtest app or extension but the actual descriptions says it's not monitored?? does firefox have a secure internet speedtest? why are these blank?? We've made some educated guesses about your current browser and operating system

is this support or forum??

On Feb 13th I went to my website at MyHeritage.com, to which I'm always logged in, to find that a few seconds after it loads it becomes all greyed out and I can't access anything. I had been on the site a couple of weeks earlier with no problems.

I removed the "Enhanced Tracking Protection" and I turned off AdBlocker for the site but the problem persists. I have logged out and then logged in - same problem. I turned off my computer and restarted it - same problem.

When I went to log in to my account at MyHeritage using my Chrome browser I encountered the same problem of a greyed out page BUT there was a banner stating something about cookies and when I clicked the "I understand" button the greyed out page cleared and I was able to access my account.

However, Firefox is my default browser and I want to be able to access this page using Firefox. It seems to have something to do with cookies.

If I go on any website using OSM data (including OpenStreetMap itself) on Firefox logged into my account, I experience a lot of slowdown. This doesn't happen when I use incognito mode or when I use another browser, so I'm pretty sure there's some kind of cache or something that's connected to my Mozilla account that slows down OSM massively. I've tried clearing all cache and all cookies. I've even refreshed Firefox using the installer and it's still slow. I don't want to bother with deleting my account and creating a new one. What should I do to try and return back to normalcy on OSM?

Hi,

I've been getting a glitch while typing emails in Outlook Web Access for the last couple of days where superscript type in dates looks like the image attached. It was working fine until sometime this week. I've tried using Microsoft Edge and the issue doesn't happen so I'm thinking it might be browser specific.

I'm running Firefox Version 135.0.1 (aarch64) on a Mac Studio with Sequoia 15.3.1 (24D70).

Can you advise please?

Thank you very much.

Calum.
