I would like to control the animation speed of .GIF (ie on Wikipedia). I would like to stop, manual single step or play frames one per duration (ie 1 frame every 2 sec or 1 frame every .5 sec). I would also like to control whether it repeats. I would like to freeze at any point then resume playing given the above settings.

How do I do this?

PS: There may be other types of animation files which the above control could apply to as well.

Thank you kindly for any guidance!

I am running the latest public stable release of Firefox, 151.0.1 (aarch64), and these last few weeks I've been getting prompted to grant my location over and over every time I do a Google search. In MacOS, I've granted Firefox location permission and I've repeatedly saved me giving google permission but it doesn't stop. This is happening on my MacBook Pro and Mac Studio.

Anyone else? Any tips? It's maddening. lol

I use Linux Mint and I have been experiencing numerous system crashes involving Firefox which requires a cold boot. What is the problem? How can I debug this? Are you getting crash reports?’

This happens several times a week. It has happened continuously tonight since installing the latest update via the Software Manager.

The program causes a total freeze of the OS. All other running programs and all input sources. I have no choice but to shut down via the power button on the tower.

Mint generates crash reports but I have no way to determine if they are being sent to Mozilla.

Firefox for Linux does not provide a troubleshooting system like it does on Windows. Neither does Mint.

I studied Computer Science in the 80s when Firefox was known as Navigator. I learned C and the Unix OS, but since then I became a psychologist, and don't remember too much of the Com Sci stuff I learned and I don't think Mint allows user modifications anyway.

What can be done to fix this? I don't have the Benjamins to buy a new Windows to replace the Linux, nor do I want to.

I like the concept of having various news articles & topics of interest on the Start Page. However, I don't like the fact that many of the links take me to "subscriber only" sites, and ones that I have no subscription to! We should be able to eliminate those sites we can't read the articles on, it would be pretty easy to have that option, instead of our having to waste time, going on wild goose chases!

And I first attempted to log in to the feedback & suggestions page, however Firefox's own password auto-fill, kept putting in the wrong password, (one for a completely different site), and when I searched to find the correct password, it was too late. Soon as I entered the correct one, it locked me out, saying too many consecutive attempts had been made! To make it worse, the error message gave no info as to what my next step should be!! It didn't say to try later, how much later, provided no link to a page to reset my password, no "forgot password" option, nothing. Why is logging in on Mozilla's own, various sites, always seem to be so buggy? I've had more issues just trying to log in, than I ever should have, no idea why this happens so often, although with the auto-fill inputting the wrong information, that could be one reason.

I have no idea what is happening. Whenever I try to use youtube on firefox the site just freezes. I can still scroll up and down, but nothing that wasn't already loaded loads, I can't click on anything, and nothing except scrolling does anything.

The reload, home, and even screenshot buttons don't work in these frozen youtube tabs. The only way to do anything is to open a new tab and close the frozen youtube one.

Youtube is completely unusable because of this.

I turned off every single addon, I restarted firefox, I restarted the entire computer, I tried in a private tab. It still freezes every time.

I don't have a VPN, I do not have the problem on any other website (even other media-players), and I don't have a clue what is happening.

I do have youtube premium.

Any help would be appreciated. I need to watch stuff for my studies but I just can't

Operating system: Windows 11

I had to turn off Norton VPN to use Thunderbird as my email client for the Comcast email service. Is there any strategy to allow Thunderbird to work through a VPN? I use the POP protocol and keep all saved messages (hundreds) on my PC, not on the email server.

After the latest update, a website I use (https://compcon.app/) started throwing the following errors:

downloadable font: CFF : Failed validating CharStrings INDEX (font-family: "Helvetica Bold" style:normal weight:700 stretch:100 src index:0) source: https://compcon.app/assets/Helvetica-Bold-DaBjwqT2.otf downloadable font: CFF : Failed to parse table (font-family: "Helvetica Bold" style:normal weight:700 stretch:100 src index:0) source: https://compcon.app/assets/Helvetica-Bold-DaBjwqT2.otf downloadable font: rejected by sanitizer (font-family: "Helvetica Bold" style:normal weight:700 stretch:100 src index:0) source: https://compcon.app/assets/Helvetica-Bold-DaBjwqT2.otf

It can't load the font the website is asking it to use and is replacing it with a default one instead.

Do you know how to fix this? Either on my end or theirs?

Hello, I went from being able to reopen Mozilla and have all tabs open. This stopped happening a couple of days ago. I do not have the restore previous session as was suggested to try when I searched this topic. I went into manage history, import and backup, restore, then selected the most recent date available. At first it didn't seem to work and I started searching through history to reopen tabs one by one. I left my computer (still running) came back and all my tabs had miraculously reappeared. I checked my settings to make sure nothing had changed. It hadn't - still set to reopen tabs when opening Mozilla. Closed the laptop last night, This morning - no tabs!!! I have a lot of tabs, and groups of tabs, with info I need. How do I recover these tabs and stop this from happening again? Thank you.

When using the official Firefox AI sidebar integration configured with Gemini, the user authentication status is not persistently maintained. Every time the sidebar is minimized/closed, or when switching within the sidebar interface (such as clicking away to view Chat History and returning), the session state is destroyed. The sidebar immediately defaults back to a generic splash page prompting the user to "Sign In" again, effectively breaking the seamless chat experience.

Hello, Im using localized (Lithuanian) version of Firefox. Several updates back, Firefox started including russian and Polish in preferred languages by default. Personally i know how to remove those for myself. However, since im managing around 300 computers in a school. This starts to become an issue. In Lithuania we only have one official language. And when pages in a school start opening in foreign (russian) language this starts to be quite annoying. I would love to keep using Firefox but i need help.
