Diễn đàn hỗ trợ Firefox

If I do a Google search for a Wikipedia article on a fresh launch AFTER going to Help/Troubleshooting Information/clear the startup cache, the page renders as attached. Other pages also render oddly like this at random.

Have refreshed Firefox - no effect Tried launching with addons disabled - no effect Default theme - on, no effect Hardware acceleration off - no effect

Launching in Safe Mode DOES seem to fix it, but I cannot keep working in safe mode - anyone any idea?

Clearly something in Safe Mode is being deactivated beyond addons etc

ever since the most recent update last night, these horrid blue boxes have appeared around every intractable element once clicked on (except on complex js based websites like twitter and youtube), no amount of farting around in about:config nor even using troubleshooting mode has gotten rid of them. caret browsing is off. windows' narrator is off. ive also tried disabling all of my plugins, which had no effect

it appears to be the exact same issue that this user was having. i tried all the solutions in that thread. no dice. i have also tried all the solutions in this reddit thread

ive attached a collage of some examples below.

ive tested these same sites in opera gx to compare, it does not exhibit this faulty behaviour.

i need this fixed as soon as possible as firefox remains my daily driver due to being the only browser that still has good plugin support and decent customization

This release changes the function of the 'wheel' on a mouse.

Instead of scrolling up & down a page, it now 'zooms' in and out.

Is this deliberate? Or, is it a bug?

Microsoft USB Basic Optical Mouse v2.0

Since the last but two update. actually in January. this is what has happened to the message boxes on MSN. That is someone replies to me through a comment and a box with the reply pops up. This is the result.

On my early 2009 iMac, the drop down search engine selections in the tool bar search bar flicker on and off and will only appear stable to be selected a search engine if the Command key is held down.

A certain website (flixbus.com) is getting pinned on my firefox automatically. I have unpinned it several times but after few seconds, it gets pinned again. It's driving me nuts. I even cleared all my cookies but it didn't help.

I have a new laptop so needed to install an adblock. The search results page gave many choices. However, no matter which one I clicked on it said this page is not available in your region. Now how is that possible seeing as on my previous laptop and in the same region I could install the add on? I have had to use a VPN to install the adblocker. Please explain how regions prevent the installation and why it happens. Firefox is universal or so I thought.

Please let me know what I can do to make Firefox more functional on my Mac. If I keep having to uninstall and reinstall every few weeks, I'm going to have to use a different browser.

I recorded USB webcam pictures with MJPG_streamer and converted them to mp4 using

  ffmeg -r 20 -pattern_type glob -i "*.jpg" -c:v libx264 test.mp4

Firefox complains "video can't be played because the file is corrupt" Google Chrome and VLC have no problems playing the file.

What options for ffmpeg do I need to create the mp4 files so that firefox can play them?

How do I add the icon for an add-on which is not shown when I click on "customize toolbar"? When I click customize toolbar the result does not show any of the icons for add-ons/extensions.

i lost my bookmarks and saved passwords data saved in my account by resetting the password.

Please help me how to get my bookmarks and saved passwords data.

When Firefox automatically updated to 109.1 tonight, I lost all my saved passwords and bookmarks. The bookmarks aren't in a file under 'Restore' in 'Manage Bookmarks' (but I had saved them so I got most of them back). But I can't get my passwords. What happened?

Since the update a few days ago, Firefox is crashing and some sites such as Trust Pilot, do not work at all on Firefox. I know it is Firefox because it works fine with Chrome. Even Google Search does not work right.

What is the problem?

Hi - Firefox has been randomly crashing a lot lately for me. Here are the report numbers - bp-d13cc7f7-782b-4308-a209-751540230320 bp-c3c23d0b-0e10-44cd-aa24-9f86f0230320 bp-4206a498-bc21-45d4-91b8-2edb40230320 bp-230d21d1-0527-4806-9da1-9aa8b0230320

I am new to Firefox and I have no idea if I have setup everything correctly to secure my PC? As a Pensioner I am finding this extremely difficult and have no idea where to or how to get to any of the pages in Firefox to check if I have correctly secured my PC? Please would someone be kind to take control of my PC and check for me please? I would be most grateful for you kind assistance herewith.

Many thanks to all those who take the time out to assist others, we appreciate your time and kindness.

Thank you

Everything that has an active state seems to have suddenly gained huge thick borders, usually grey or black. This applies to UI and page elements. I have no idea what happened, I'm guessing an update changed 'something', but how do I nondestructively fix it?

All webpages seem affected.

(reddish bars in second screenshot are my removing some URLs, but everything else is my UI as seen)

Thanks greatly for any insights...
