AVG has ended Online Security Add on for Firefox and AVG has told me that I may not be secure when I use Firefox. How can I stay secure on Firefox. I do not want to have to use any other browser.

I've migrated to Firefox from Chrome and am getting everything as close as possible to my Chrome setup. This is a usability issue when I zoom on an image, that has a larger version. Chrome allows me to zoom to the full extent of the image, but Firefox screen shakes and doesn't allow the same detail. Screen recording and links below.

Sir, my hp desktop PC is having -- windows10, Firefox, connect cable Broadband with 100mbps speed, Ethernet, periodically updated. I am very much fond of watching English/Foreign language movies having English CC/Subtitles, online streaming, generally on paid channels e.g. Netflix, prime video, Hotstar, you tube etc. I am not proficient in English language. To read the English CC/subtitles, I have to pause the streaming, read the subtitle and then start the streaming (pause-start, pause-start). After about 15 minutes watching the film, the screen becomes black (no video), with a no signal detected message. But audio/sound remains continue. Then I switch off the PC, restart it, and watch the movie for next 15 minutes., then again black screen.This cycle goes on. But When I watch the film continuously, without pause-start function, then there is no black screen problem. In my opinion this repeated pause-start function causes the black screen problem. Without pause-start function, I cannot watch these movies. I tried some online mentioned solutions without success. Please help me in solving this problem in a simple way as I am not perfect in computer science. Regards.

Hi,

I'm experiencing a problem on Firefox 125 and 126 on Red Hat Linux 8 & 9 and also on Ubuntu 20 and 22 systems.

We have a proxy pac which we have tried loading from an http url, or a local file and both produce the same result.

• Launch Firefox, no access to Internet sites (i.e. no proxy)
• Enter settings and Reload proxy pac
• Proxy works perfectly

Is there any way to force the proxy pac to load on Launch? Why isn't this the default behaviour? or am I doing something wrong?

Thanks

The menu bar at the top of Firefox is extremely small. The size is about 1 mm. I have tried all the supposed fixes and none of them work. I have a new Macbook pro using Firefox.

Once again Firefox has decided to take over and change all my settings! I had finally managed to prevent it updating, as each and every time I had to reinstall all my setting and extentions from scratch. Today, it decided to clear all my preferences and change itself to its own default settings. OK, so I can change my profile option, except all three are using the same defaults: I appear to have lost all my settings and extensions entirely. OK, I'll copy from my backup, but once again the three backup profiles are being overwritten with the defaults. Even my third backup of last March overwrites to the defaults! How and why is Firefox managing to keep overwriting my defaults to its own preferred settings? How do I stop it doing this and regain my own preferences?

I also tried Sync and now I am getting bookmarks from over five years ago! And once again my settings are changing to the defaults. Surely a Sync should overwrite with the current bookmarks and settings not just keep adding more and more. I am now in a right mess again. Back to losing everything with updates. I am a great believer in the 'if it ain't broke don't fix it' mentality, but Firefox has broken itself and is refusing to allow me to change to how it used to be! How do I restore my own preferences and prevent Firefox from changing them to what it wants.
