Why does Firefox prompt for system handler when first word in search contains a ':'?

Recently, when I copy and paste an error message to the search box in Firefox and the first word contains a ':', such as when searching for this error message - "MESA-LOADER: failed to open dri: /usr/lib/x86_64-linux-gnu/gbm/dri_gbm.so: cannot open shared object file" - I get the "Open the mesa-loader link with System Handler?" prompt (see screenshot).

I used to be able to copy and paste such an error before into the search box and it would just work but now the browser defaults to thinking you are entering a URL. This could be because when I start typing in the search box, it immediately relocates what I'm typing to the address bar. Maybe this is the behaviour I need to disable? But how and why is it the default?

Help!

Hello there. Unfortunately, according to Netflix help pages, Firefox Linux is limited to 720p, unlike Windows or macOS version. Opera is the only linux browser allowed to stream Netflix at 1080p.

This is a Netflix side limitation because using a fake user-agent is a workaround.

I have reported this problem to Netflix, it appears to be a DRM limitation. My report to Netflix have been share with their tech team, but I doubt that leads to anywhere.

Question : why this limitation ? Is the Widewine codec implemented differently in linux version ? Is there a way to make Netflix change their rules from Firefox team ?

After the update, a window popped up asking me to select a profile. But my profile, where all my passwords, bookmarks, etc. were, was gone. I couldn't restore my bookmarks because the only one available was from today and it`s "clean." Is there any way to restore my account data? Because everything was there: settings, bookmarks, passwords, history.

Hi, I recently switched to Firefox and I have run into a problem. While printing a pdf on the "more setting" menu the percentage scale doesn't actually work. First of all the preview doesn't change when trying different scales, I thought that it might have been a preview problem and I've tried to print anyway finding out that also the printed result wasn't correct. I often use this feature and I will be grateful if you are able to help me. Thanks

Hello, I reset my PC yesterday.

I didn't know my Firefox password anymore and clicked "Forgot password."

Then I created a new one.

Now my saved online pages and everything else are gone. So synchronization isn't working.

I have an account recovery key.

Will that work? And how?

Please help me.

Was prompted to download a program to Firefox before I paid my phone bill. I did not recognize the web address or name that was shown, and the account number from which recent payment was deducted did match any accounts I hold or held in the past. I cancelled the action immediately, without downloading, but am still concerned. I found nothing on the internet about this, just got a summation chat AI response that stated the phone company had no download/extension for Firefox. Has anyone had any experience like this or could someone shed some light on this?

This wave of so-called AI (really nothing of the sort) is a nightmare for security, usability, performance and efficiency and if you keep forcing it on us I'll be jumping ship, probably for whichever fork excising it all gets popular.

I've been using first the Mozilla suite and then Firefox (since it was called Firebird, even) for twenty years now, don't do this to the browser I love.

Hello. I'm having a sudden problem. Both the regular search screen and the image search screen are misaligned, overlapping the search box, or showing through. I have no idea what's causing this and don't know what to do. Restarting the computer doesn't work, and disabling add-ons doesn't work either. The cause is unknown. Windows 11 Home Windows version is 23h2 Firefox version is 144.0 64-bit.

I had two Firefox windows on my computer, one with a few tabs of Youtube and Twitch pages, and a private window with a single Twitch stream. I've had them and the program open for days, with my conputer turned on and off multiple times with no issues.

Today I booted a game I installed yesterday on my computer and played for a few hours, after closing the game, both my Firefox windows became completely inaccessible.

I've tried closing firefox, restarting my computer, letting Firefox create a new xulstore file and nothing has worked. I can't see the window, I can't make it active. It's permanently minimised.

It spikes Desktops Windows Manager to 100% GPU usage, it makes my PC lag and run slow, and I can't do anything in the browser cause the window won't stay open or up. I can't even open the old window and then a new one, it stays minimised and I can only see the preview by hovering my mouse over it.

I've tried GPU driver updates, I tried anti virus scanning, and I've tried opening another browser which did work. But Firefox is the one with all my saved settings and preferred browser. I also can't see the Firefox window at all when using the window key + TAB to check my desktop, but it does show up on Task Manager as running.

Please help me restore my program. I'm making this on my phones firefox browser which is running fine

Hello why my firefox installation 1440b6 64 bit on windows 10 do not autocomplete the third field in a form login ..

namely , username and identification password are correctly filled , but the third field (that in my case are named "company ID") would not, it remain empty, and i need to manually fill in each time. Actually this happen only on a one site , but may be because only this site that i use have a three field to fill in the login page...all the others need only password and username

thankyou kind regards klx140
