_05: chrome browser network panel after refreshing 5 times domContentLoaded: 328ms

_06: firefox browser network panel after refreshing 5 times domContentLoaded: 1880ms (5.73x slower)

the problem seems from that the request from firefox gets 200 wheras chrome gets 304 unmodified, which explains the huge speed difference in reloading.

In the pre-Webextension days, there was an add-on that allowed one-step install/run of downloaded executables. It worked like this: When the option was selected, the executable was downloaded into a temporary directory, execute it from there, and finally (optionally) delete it.

Now I only do it manually.

Ironically, MS Edge has this functionality built-in (see attachment).

Is there a way to achieve this on FF?

I am on a Mac M1 and up to a month ago I was using the latest version of Firefox (regular) and the last few weeks it had this issue and when I switched to Firefox Dev Edition it went away until today.

The issue is defined as when I right click on a link it left clicks and right clicks on the link at the same time. (It loads the page I clicked on and also triggers the context menu)

I have no themes, no extensions.

Anyone have any idea how to fix this? It's not happening in Safari or Chrome (both latest versions) and it took me years to finally migrate to Firefox and would hate to go back.

Thanks in advance!

Using Firefox Developers edition since the update to 109.0b3 (64-bit). The scroll wheel doesn't work, the mouse button I have mapped to the back button no longer works. If I launch Firefox in troubleshooting mode everything goes back to normal and the mouse performs perfectly in troubleshooting mode. Back in normal mode I have tried disabling all three of my extensions and the problem persists. Mouse performs perfectly in every other application. Sounds like a bug, but I can't find anyway to report it. Any ideas? Thanks

Had to refresh Firefox but lost my bookmark sidebar & can't find a way to re-establish it. Used to be a setting for it at the top of the home page but none now. Can't find it in settings.

For some reason text on some websites such as wikipedia and timeanddate is completely messed up, it looks like gibberish but is actually just displayed wrong. When you copy the text and paste it into something like Word it shows the text correctly, I've noticed that the text is shifted by one letter forward (e is f, f is g, etc.). I've tried the main, beta and nightly releases as well as reinstalling Firefox. Images attached.

Hi!

I like to have my browsing history cleared after I quit Firefox, but I found out that this will break the action to open previous windows and tabs.

How to have these two options live together?

I have recently updated my site to run off a different hosting provider, and CloudFlare, a long needed change to my site. However, in doing so, my site has become unreachable on my laptop, with firefox (and other browsers) still thinking that my domain is attached to the old nameservers, causing it to redirect to the "site not found" page of my previous hosting provider. I have tried flushing my system's DNS cache, clearing my browser cache, clearing the browser's DNS records, all to no avail, however, I do know my site works, as on my mobile phone with basic Safari, the site works fine.

my system is on Ubuntu 22.04, and running firefox version 107.0

Is there a way that I can recover my New Tab page setup (just the new tab page) from a Macrium Reflect backup of my OS disk? I recently did some cleanup that cratered my FireFox profile (developer and beta also). I would like to somehow recover just the New Tab page setup from the os backup. Any solution? Thanks for your help.

I've recently been having troubles playing videos on Firefox.

My school website uses Vimeo embeds, but recently when I've put the videos in fullscreen, after 4-5 seconds it stops responding. The video freezes but the audio continues, and the controls don't come up when I move the mouse. I can press ESC to exit fullscreen, but the controls are still gone and the audio keeps playing. Then after a few more seconds I get the warning "This page is slowing down Firefox, to speed up your browser stop this page".

If I don't use fullscreen but instead zoom in on the page, it also freezes. If I try the same things with Edge it does not freeze. I also made sure that it was only affecting Vimeo videos, by testing with other platforms and other vimeo links.

I found previous reports of this issue, but all of them were either on Linux, or it was an issue with flash player, which is not relevant anymore.

Not quite sure how to debug this but I would be happy to provide further info. It's really important that it works again :/ Thanks in advance!

My repro steps: 1. Find a video on https://vimeo.com/watch 2. Play it and enter fullscreen 3. Wait around 6 seconds

I have a laptop with Ubuntu 22.04. Firefox 307 from deb package works perfect. I wanted to give a try to Flatpak variant 306, which works well too, except two finger gestures back and front won't work. Scroll works. Any scheduled fix for that? Would be cool to move to flatpack completely.

Every time I work on the local environment a lot of my extensions go crazy on localhost, throwing enormous amount of errors. This makes console barely readable. Is there a way to disable messages thrown by extensions in the developer tools of Firefox Developer Edition?

Similar to this in Chrome with "Selected context only": https://superuser.com/a/1346827

Thanks.

Hi, lots of good support to how to sync. No support for how to view synced tabs on an iMac. I can see the synced tabs and open them on my iPad and iPhone. Thanks for your assistance.

Hello, We are developing an extension which is built on manifest v3. Right now in the firefox MV3 is not available by default and user has to enable it manually. I wanted to understand the timeline for the MV3 release. So that we can decide to support MV2 or not in our extension

I run Firefox Developer Edition.

I recently added some lines to my hosts file (C:\Windows\System32\drivers\etc\hosts). Despite these additions, Firefox ignored the hosts file and loaded the pages I had blocked just fine. So I tried a multitude of options like disabling "Enable DNS over HTTPS" and eventually I got to work and the hosts file was respected.

So after thinking about it for awhile, I actually DO want Firefox to ignore the hosts file like it did before I made the change. I reverted the "Enable DNS over HTTPS" setting to its default of enabled, and I've tried everything else I can think of, but I just can't get it to work.

How can I configure Firefox to ignore the system HOSTS file and load blocked pages anyway?

Could really use some help.

The new update just installed. What happened to my palm frond home page look!!?? I loved that. How can I get it back? OR at least, where do I go to change what this looks like and pick something else?? - Eileen

I receive this error message for several sites that I know are secure (i.e., dvd.netflix.com): "The page you are trying to view cannot be shown because the authenticity of the received data could not be verified." How do I override this?

Hi, I have been a Firefox user for 30 years, so I want to comment on your product. Every year I notice the performance of the browser getting worse and worse, more and more errors unexpected closures and slowdowns, it's bad to work because such small crashes make you look for another alternative. I do not write this maliciously, but that you think about how to improve the performance and speed of firefox. I only hope that someone wise will read this and pass it on to the higher-ups to make real changes.

In any case, you are going in the right direction and I still consider firefox with the most friendly and easy to use browser.

greetings to the team
