Is there a way to use a list of sites you want to block with the manage exceptions option in settings. Several times now I have gone to the option and found it empty of entries, having to replace the sites I need to add one at a time blocking and reopening the option for each entry. Two things would be of great help: 1. find out how the manage exceptions option is being cleaned out and stop that action from happing 2. I have prepaired a text file listing the sites that I feel I don't want cookies from, a way to enter that list as a group (batch) into the manage exception blocking setting at least would make the work faster.

I enter the list to my host file also block them with my firewall witch dose some good on the house side of the blocking but little on the browser side.

anyhow any of this you can help with would be great. Don Smith smitm13@msn.com

I formatted my computer and then when I had to login to my Firefox Browser. It was not taking any of my old passwords. So, I had to reset my Firefox Sign In password. After the password was reset and sign in. I couldn't find any of my previously synced bookmarks. The synced bookmarks are extremely important for me. I need them back. Kindly suggest and show some way to get them back. Please help. Please Please,

what can i do to restore my synced data.??

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.

My menu items are now (9/7/2021) White and double-spaced. Why does FireFox change things that don't need changing with no path back. First, they changed menu color to default to another (I think same as Toolbar color) with no recourse. Now the menus are white and double spaced (today! out of the blue sky!!). FireFox, at LEAST make these features configurable. Why do you do this?

Firefox prioritizes IPv6 (even on a network with internet-accessible fd00:: address, which contradicts my currently set up prefix policies) over IPv4. Now the problem is that my IPv6 address is a tunnelbroker.net one, and while I still want to be able to access the IPv6 internet, I don't want a tunneled connection to be my default. And I don't want to disable IPv6 completely. Is there a way to force Firefox to prioritize IPv4 over IPv6?

Note: the first time when connecting to a website, the browser connects via IPv4 (like the prefix policies are supposed to work), but then it remembers that the website is accessible via IPv6, saves it into the content-prefs.sqlite file (removing the said file makes the connection fall back to IPv4 first again) and connects via IPv6 again. Is there a way to make Firefox NOT remember that in content-prefs.sqlite and still connect abiding the prefix policies?

Using Firefox Dev Edition 103.0b9 on Windows 11 x64

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.

I am constantly frustrated by unresponsive pages / script warnings etc using Firefox. This never used to happen on previous builds -- I am using the latest 86.0 -- but these occur so often that I am about to say goodbye to Firefox. This does not happen when I am using Chrome and other browsers.

I have been through all of the suggested steps to deal with these unresponsive script/page issues, and none has worked.

Would appreciate any help on this, but as I say I am about to leave Firefox at this point for Chrome and other browsers.

Thanks in advance...

I'm trying to customize colors of Firefox developer edition. I would like to have a dark toolbar bit i don't wont to enable dark mode for any website.

I have installed Firefox color and whenever i choose a darker color for the toolbar all websites are displaying their dark versions (it behaves like the dark mode is turned on).

I have tried to manual set browser.theme.content-theme and browser.theme.toolbar-theme but after every restart these get overridden.

Does anyone know how to make this happen?

The funny thing is that everything was fine before today's update...i tried reinstalling Firefox and also i tried disabling all extensions...

Firefox version: 102.0b7 OS: Win 11

While watching videos(movies/anime) video takes much time to buffer. If video is of 20 minutes then it loads first few minutes then after watch time reaches that buffered video then it takes more time buffer.

What I am looking is for, how can I force firefox to buffer full video at once or is there any way to increase buffer size.

I just installed the latest Version of Firefox 101.0 for Windows 10. Then when I tried to download a pdf file from my yahoo mail I received the following message: "Problem loading page" Firefox Can’t Open This Page To protect your security, dl-mail.ymail.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window. Learn more… Open Site in New Window Report errors like this to help Mozilla identify and block malicious sites

So, in order to open the page I have to press "Open Site in New Window"

Please advice why happened this issue and how can be fixed.

Trying to use throttling (eg. Regular 3G) in Network Tab.

In developers edition, any Throttling setting (other than "no throttling") never loads any website. Just white screen.

Creating a new profile and not making any changes to it, did not change anything.

When will Mozilla introduce RTX Video Super Resolution technology to its Firefox browser?

My account is not syncing to any Firefox browser, extensions, passwords, bookmarks non of this attributes will be loaded to my browser back after re-installation, What might the issue be?

With Firefox 91, I can no longer disable the hideous Proton changes to tabs. Separating tabs from their content is a really poor user interface decision. It makes it harder to tell which tab is the current tab. With Proton, the active tab is slightly brighter than the inactive tabs. For older folks and color blind folks, this makes it all but impossible to to tell which tab is active.

If you won't come to your senses and revert this bad user interface decision, then at least add an official option to disable it and go back to the old tab style that other browsers use. If you won't do that, then I will just have to use a different browser. Which makes me very sad, because aside from your bad sense in user interface design, I loved Firefox.

I have had it with Firefox playing cop. I really have. I have a site that I visit frequently but these past two updates have now broken my ability to sign into the site at all, even in private mode. All I get is the shield and human icons with the strike-through and the error message on the user name/password field that says: This Connection Is Not Secure. Logins Entered Here Could Be Compromised. Learn More.

I've hit the escape button, tried private windows, done everything I can including resetting which was my last resort and which I hate doing, there's no more whitelist, no way to bypass anything, this is totally unacceptable that I cannot get past this. Firefox is becoming more useless to me as they try to become more and more in control of what I can and cannot do. If there is no override to this, then I have to find a different browser because it's pretty useless to use one browser for some sites and another for other sites, don't you think? So if someone has a workaround for this problem, can you please tell me what it is?

Bought a new windows 11 ASUS laptop. Trying to install an HTML bookmark file from older windows 10 ASUS laptop. When I execute the HTML file import on my new ASUS windows 11 laptop, nothing happens. Even found and removed the "block protection" in the HTML file.

Why am I unable to import a firefox bookmark HTML file?

Thanks for any solutions anyone can provide.

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

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.

Recently I got a Mac computer and I installed Firefox in it. I can't find "About Firefox" in Application Menu.

How to show it in Application Menu like Windows and Linux?
