Why doesn't my zen browser use enabled and working hiddify? Instead it shows my real IP address, not the VPN IP address on sites like "https://whatismyipaddress.com/". I am using Ubuntu 24.10.

Hello, I recently had 20+ tabs open in Firefox. I moved 1 tab of the 20 to be a separate page and closed the other tabs. Now I am unable to re-open the other tabs through the 'Recently Closed Tab' feature. That feature only shows a few new tabs I opened on the separate page. Is the only option to painstakingly search through history over several months to re-open several tabs I had open for several months? Thank you the feedback, Ken

I am installing an extension I trust, called KDSpy, to help me see which books are selling well on KDP Kindle Direct Publishing. How can I go back to click the box "run on private browser" for incognito browsing?

Using this digital card https://www.sendoutcards.com/act/XNBFQFHHNO , the images are squished together instead of displaying correctly on inside left and inside right. On other browsers, like Chrome , Opera, and Edge, they display correctly Why?

Hi! I'm experiencing an issue where videos on YouTube stutter or play choppily when using Firefox. This happens even when the internet connection is strong and works fine in other browsers like Chrome.

Here’s what I’ve noticed:

The issue occurs on both 720p and 1080p videos.

It’s more noticeable when switching to full-screen mode.

I’ve tried disabling hardware acceleration, but it didn’t help.

Firefox is up to date (v126.0).

I’m using Windows 11 and have an NVIDIA GPU with the latest drivers.

I’d appreciate any suggestions or fixes. Thanks in advance for your help!

Hello,

NVIDIA RTX Video Enhancements are not working in firefox at all. By not working, i mean neither Super Resolution neither HDR enhancements work at all, not even the badge shows up, and the NVIDIA app reports the status as "inactive". The video is not upscaled, and the content isn't getting put into HDR. It is on globally on my system, and does work on all the chromium based browsers installed on my system, even on the discord app itself.

I tried a latest firefox fresh install, with youtube playback, or just opening a video file directly with the browser. This worked on chromium browsers, but not on firefox.

I'm on windows 10 64bit with a 3060 gpu. (the only gpu in the system.) I have 4 monitors connected, but still get the same issue with only one. Hardware decoding is force enabled, and about:support reports that hardware decoding is supported for H264, VP8, VP9 and AV1 too. I even get the same amount of video-decode usage in task manager on both chromium and firefox while video is playing.

Thanks in advance.

After a recent update, certain websites (like Youtube) leak script that remains even after the tab is closed, until Firefox is closed. When one of these websites is accessed for the first time, a second tab opens and quickly closes, as if a popup was blocked. One way I can observe this behaviour is that the NoScript extension will detect script for that website on ALL tabs, even blank ones, with the "(sidebar?)" annotation. With Youtube I managed to prevent this by disabling Service Workers in about:config, but for example with tenor.com the behaviour continues to occur even then.

Websites I observed this behaviour on so far: youtube.com (until Service Workers were disabled) tenor.com nami.news

Is this a bug? I have also observed the same behaviour on a different PC for Youtube until I disabled Service Workers on that installation. What should I do?

I use several browsers and when it comes to functionality I consider FFox to be the best however with 1 major drawback - it's speed / lag issues which is why I stopped using it as my primary browser and only as secondary one

I can have 2 different Chromium based browsers open simultaneously and while this impacts the performance somewhat if I open Firefox and another browser responsiveness grinds to a halt (sometimes even crashes)

Even just starting Firefox by itself takes 5x as long as other browsers

So I'm wondering is Firefox just more resource intensive or is there something wrong with my setup?

The main difference between my Firefox install and my other browsers is the number of Bookmarks (10000s) due to me having it installed for much longer so is it possible for a large number of Bookmarks to slow the browser down even when not open ?

Other possible causes I read elsewhere are 'Cookies and site data' (currently around 50mb)

I clear the 'Temporary cached files' & 'Browsing history' on regular basis so they shouldn't be an issue

The add-ons I have installed are NoScript , Ublock Origin & Firefox Color

In regards to troubleshooting is it possible to install a 2nd install on the same system simultaneously without overwriting the current one ?

Thanks

One of the add-ons I use has been permanently disabled. However, the email that the developer received says "Users who have previously installed your add-on will be able to continue using it." Why can't I use it?

Some of my shortcuts were missing on Firefox when I started my laptop this morning. I tried restarting my computer but that didn't help. I really don't know what topic fits best. I am not at all tech savvy when it come to computers.
