I haven't installed any new Add-ons for over a year but suddenly today the Telegraph.co.uk website is only displaying images. I disabled all Add-ons, re started FF but that hasn't fixed it. Safari is okay though. Mac 10.11.6 and FF 78.10.1esr Thanks for any tips, can't do without a proper newspaper. Kryters.

Two questions re: the forced update from 78.15 to 91.

1: Will all bookmarks, and all other settings be retained? Is there a form of recommended backup in case of problems (I currently use MozBackup, still)

2: Will the "Bookmark Tab Here" add-on work with 91? I need a user friendly bookmarking system, which was the reason I stayed with ESR in the first place.

My wife works on her Firefox browser. She can't print (nor preview) to PDF. Yet she can do this on a Safari or Chrome browser. I share the same computer, but using a different account. I have no problem printing/previewing to PDF on my Firefox browser, when using my account. This problem is not recent.

We use a Mac mini (2018), macOs BigSur 11.5.2, Firefox 78.13.0esr (64-bit)

Thank you for helping with this problem.

Hi,

I found some discussion related (https://discourse.mozilla.org/t/disable-add-ons-on-specific-website/33693) but no solution yet.

This is imho a big flaw in the privacy of users.

There are trivial cases, for example if I use a YouTube downloader plugin, I obviously want it to monitor my browsing ONLY when I'm on youtube.com...

And there are some critical cases: when I browse my web banking, or when I go on some trading website, I don't want my financial operations to be at risk because of an add-on that is very useful everywhere but on those site.

However, I don't want to exclude all the add-ons for those website too, that would be just too much.

I think there's already a coding base in place, since you can disable each add-on when using private windows. This could be enhanced by having a system of whitelist/blacklist instead. And this feature would actually make more sense than using a private window.

Another way would be to have this feature on per container, instead of per website, than would work well too.

People have different activities, and some requires useful plugins, that are very specific. I mean Keepass's add-on (for example) is useful everywhere, but many add-ons are related to one activity at a time.

For example, if I'm a marketer and want to analyze website, I'll use add-ons for having stats on metadata or keywords or even real time reports from Alexa or from AliExpress, etc...

But when I'm reading my email, I'm not happy those add-ons can see my data.

That would be tedious to disable all those plugins every time I change activity, especially since we are productive humans so obviously we need to alternate those activities doing multitask all the time.

And the private window option is not flexible enough for that kind of multitasking, when containers are.

I hope this helps everyone understand clearly why I think my request is not only a real user need, but also currently a flaw in users privacy since most people will not trade the comfort of their add-ons for some privacy concern they don't always understand...

I know this is some kind of feature request more than ask for help, but https://qsurvey.mozilla.com/s3/FirefoxInput/ is out of service so I don't know where to address my concern here.

Thanks for helping me pushing this idea forward.

Hello,

It is suspected that latest version of Firefox version 78.11.0esr (64-bit) is causing operathing systems to crash. I have not seen it on Windows platform as I am not using it. Platforms I am using are OSX and XUbuntu. The error occurs lingering on a site for a very long time. First it starts getting screen graphic errors like, some pixels are not being updated correctly. Then after a while screen starts to flicker, in a massive state, like the graphic processor is broken. In some cases with command key strokes one is able to kill Firefox, screen is back to normal and one can continue working. Facebook is the site that most commonly is causing error, but there are also other sites.

I downloaded Scribus, an open source free page layout design application from https://www.scribus.net/

link text

I can't open this application because I get a message that says: "'Scribus.app' can’t be opened because it is from an unidentified developer. Your security preferences allow installation of only apps from the Mac App Store and identified developers.

I searched the Mac App Store and it does not have Scribus. I can't afford to subscribe to Adobe Creative Cloud and I need to be able to create page layout designs, which Scribus can do.

How can I verify that https://www.scribus.net/ is a secure application site? How can I open the application if it is a secure link?

Thanks, Shelley

Firefox already has features for blocking autoplay. I use all of those.

But, some websites still manage to autoplay! Is there a way to stop those devious websites? Examples include Yahoo Finance and ESPN.

I already have Autoplay set to "Block Audio and Video" in the Permissions section of Settings. I have also gone into about:config and set the following:

media.autoplay.allow-extension-background-pages false media.autoplay.block-event.enabled true media.autoplay.block-webaudio true media.autoplay.default 5

Is there anything else I can do?

Also, does anyone know *why* firefox is allowing these videos to play?

I have just installed 91.1 ESR. On opening the first time I am offered to "Choose a theme" or "Not now". I chose Not now.

I expected that I would then be able to go into the settings menu somewhere and find the options:

• Streamlined Toolbar and menus
• Modern tabs
• Fresh icons and clearer messages

I do not find these under Settings nor under the installed Themes. I'm not even sure these are a Theme as much of a Style??

Any help on this is appreciated. Searching the title was of no help.

Hello together,

when implementing canvas graphics with 2D context, I notified that the latest FF 87.0 on windows is much slower than chrome/edge/opera on windows and also much slower as safari on mac. I drilled into detail and detected that it was caused when drawing polygons with color gradient (see attached image). Means that using canvascontext.createLinearGradient() instead of flat colors makes it slow. On the other hand using flat colors is perfectly fast.

I wondered, because I had much better experience with FF and installed an earlier version (78.9.0esr) on the same windows workstation and the problem was gone. Seams, that some change made the newer FF slower with this type of graphic..

CPU is i7 8650U 1.90 - 2.11 GHZ, OS is Windows 10 version 20H2

But the effect is the same on all windows workstations I tested. Would be happy to see, that I can use FF again with these type of graphic apps.

By fixing the very first option you come across as soon as you go into General Under "Startup" The setting called "Restore previous Session"

Usually, a checkbox, is a boolean ON OFF.

Once more, this leaks data. For instance, logging into my webmail rebooting the machine, next time i launch firefox it spawns the same session again. This contradicts with the very first option under "General" -> Startup

If this was a public machine, some one would now have access to my email.

It seems that this is OS specific. But really, i don't care. My complaint stays the same. The option is broken, and firefox leaks data therefor. I no longer trust Firefox. This sort of stuff is not done deliberately.

Once more. perhaps bit logic is too complicated for you UI designers and a quantum gyro is more to your liking? Cause this is NOT normal.

Hi,

I think I broke the ALT keyup events in some way, probably with my configuration but not sure how.

If I put this code in the console : `document.addEventListener("keyup", e=>console.log('alt: '+e.altKey+' | '+String.fromCharCode(e.which).toLowerCase()));` and the press the keys, I have the following results:

- pressing "I", I get the expected "alt: false | i" - pressing "ALT+I", I get "alt: true | �"

I do not have the problem with other modifier keys like CTRL

We are running FF ESR 78.14.0. I see that ESR 91.1 is now out. I have seen this article on Firefox ESR release cycle, but not able to find out what the schedule is (ie overlap) for 78 and 91 releases. I am trying to do some upgrade planning. I expect 91.2 will auto upgrade and like to know how soon, otherwise I may need to manual update machines.

It would be nice if this page could be kept up to date for the relevant releases.

Driving the question is a specific issue with QuickBooks Payments not working in 78, which I am assuming has to do with something they consider obsolete security wise.

Until sometime around earlier this year, I was able to use "Import bookmarks from HTML" between different PCs/laptops, and it would always restore everything flawlessly from that backup file: all folders intact, and every single bookmark in the exact order it's been for about 14 years.

But now, whenever I use the Import feature, all folders are flattened/emptied and everything goes into alphabetical order. No matter what I do, they will not load in my uniquely crafted order (based on the sidebar, which I use exclusively). Everything goes into a single unmanageable lump in Bookmarks Menu.

Restoring from JSON makes no difference.

Versions tested from 78ESR all the way to 91. At one point, I went back to 88 and it worked fine for a day or two, but then didn't.
