When I was previously using Firefox in Kubuntu 22.04, if I downloaded something I could go to the Downloads icon and click on the download and it would open in the desired application. After a failed upgrade to 24.04 I had to do a reinstall and now in Kubuntu 24.04, if I click on a downloaded file it will always bring up a window with "Open the file link with okular?" and the buttons Cancel and Open Link below. How do I go back to the previous way of it working?

Firefox crashes every day or so on my home computer. The most common error message is "kmode exception not handled." I've tried the suggested fixes. Nothing helps. The crashes are not being recorded in "about crashes" or in %APPDATA%\Mozilla\Firefox\Crash Reports\. So it seems the crash reporter has to be fixed before the problem causing the crashes can be identified. Firefox does not crash on my office computer and no other program causes my home computer to crash. Thank you.

When using chat software, there may be shortcut key conflicts, and the sidebar will still open when using shortcut keys even after being closed.

In the settings, the AI robot is turned off, but when using shortcut keys, the options for the AI robot will still be turned on by itself and cannot be turned off.

Lost Bookmarks after Microsoft upgrade(?) Since I'm using the latest version of Windows I don't know what to call what happened that came by way of Microsoft. So far as I know, I'm the only one reporting this. It would seem that if this was a change initiated by Microsoft it should have affected millions of users.

Just recently I have found that certain sites are unavailable to me using Firefox but I can access them using Edge or Chrome. One particular one is Squarespace.

Is there anything known - how should I tackle this?

Got new desktop and cannot retrive my bookmarks. Granted old machine was 16 yrs old. I'd figure Firefox would have have a back up system. I'm 70 years young and this has got me scraching my head!!!! Not a computer expert. Thanks George

I can not remember my Sync password and it will not let me change it. Every avenue is blocked by a pop up window asking me for the password that I forgot!! This is insane!

No idea if this is the right topic or not but I've been dealing with this frustrating issue where with some websites it just loads a blank white screen. I've tried every fix I could that I've seen on forums like this as well as on Reddit and nothing I've tried has fixed it. From launching in Safe Mode or changing things in about:config. Before finishing this post I tried launching in safe mode, so my add-ons and plugins are disabled and it still persists with websites loading in these blank white screens. I never had this issue at first and I'm sure it started to happen after an automatic update a while back.

I need this issue sorted out so I can look and compare items from shops but most of the time a website that works and I look at it elsewhere I'm dealing with this issue. No issue looking at stuff on the internet on my phone, though I do use safari instead on my phone.

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.

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?

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.

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??

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
