Firefox allow to disable access to canvas for lowering fingerprinting, it's cool !

But as web developer : i like to ask this access before try to using it,

Something like :

1. Do you alllow canvas ? 2. Show the browser part 3. Wait for user answer 4. It's OK : download PDF done with canvass 5. It's not OK : shown an error to user.

To avoid such situation (see screencast)

hey folks,

since today firefox wont load any websites out of troubleshoot mode. not even settings/ about:config. if i open a page in a new tab it just stays blank and nothing is happening.

in troubleshoot mode i turned off hardware acceleration - nothing changed after restart. i updated the runtime file "Visual Studio 2015, 2017, 2019, and 2022", which is suggested in different help-posts, i deactivated all addons, i created a new profile and also tried an imported one from eralier today - so far nothing has worked.

i also reinstalled firefox with version 99/ version 101 two times, after i cleared %APPDATA%-data.

im also just using windows defender as antivir.

please elp, i'm out of ideas.

This question has to do with logging into web sites with an email and a password. Firefox 101.0.1 (64-bit). Windows 10.

On many sites, when I click in the email field, a drop down list of email addresses appears from which I can make a selection using the mouse or up/down arrow keys. Some web sites have as few as two email addresses in the drop down list, others have many more. I recall that one site has about fifteen email addresses in the drop down list.

How can I remove a non-applicable email address from the drop down list?

How can I clear the drop down list of all email addresses?

Thanks.

For some reason, whenever I load a pdf from within Firefox, I get a new tab with the regular toolbar displayed on top of pdf files, but the document itself is completely blank (see attached screenshot). This issue just started today and I assume it was a result of an update, since I don't recall making any changes to my settings (I'm using Firefox 101.0.1 on Ubuntu 20.04).

I've tried opening multiple files from a variety of sites with the same result. All of them open fine using my system's pdf viewer, as well as from within Chromium. I've tried disabling my plugins, putting Firefox into safe mode and resetting all the handlers, to no avail. Any help would be much appreciated.

I've been using Firefox almost exclusively for years now, and it's always worked flawlessly - until recently! Now, when I log into my GitHub account, I can no longer edit and commit my changes.

When I click on the "pencil" on a rendered page, I am taken to the "edit page" where I can make my changes (in markdown), preview those changes (rendered in markdown), and then commit those changes. Beginning very recently (within the past few days), the preview tab is no longer functional, and I can no longer commit my changes to the file.

I've verified that GitHub has not changed their interface by logging in from my Chrome browser, and following the exact same procedure used in Firefox everything works as it always has.

I recently upgraded from ver 99 to 100, and now to 101.0.1. I recall clicking a pop-up immediately after the 99-100 upgrade that had something to do with cookies... sorry, I know that's lame, but it's all I can recall now. In any case, I am certain this happened recently.

Please help... I have to use Chrome for a couple of things already (my brokerage account at Vanguard for example), but I despise Google, and want to limit their spying.

Thanks,

Why are google sites (Youtube, Gmail and Search) getting disconnected when all other sites are still connected to the Net? This has been happening since November 2021.

When that happens I close the FF and then immediately open it. Now the google sites work properly.

Never had that problem with other sites.....never!

Why the hell is this happening? Is FF responsible or Google?

So what is the solution?

I'm using 64-bit Linux Mint 20.3 LTS, and the latest version of Firefox from the repositories (101). Suddenly, for no reason I know, my default profile has started crashing immediately on trying to run Firefox. A small window comes up with the error message

XML Parsing Error: not well-formed Location: chrome://browser/content/browser.xhtml

     <button when-cofnection}"secure-cert-user-overridden"="" <="" pre="">

and then a line of ------^ where the ^ indicates between the t and the i of cofnection

Yes, I emphasise that I HAVE copied the error message carefully, including the mismatched bracket pair and the cofnection rather than (I assume) connection

I've managed to get a working version of Firefox by creating a new profile and using that (as in for posting this request for help), and I do have a recent backup of my bookmarks, but it will be a royal PITA if all my logins and passwords have disappeared. I don't want to go any further than this without some guidance, as all the messages I've found detailing how to fix this seem to make the assumption that I'm running Windows.

Can anybody help, please?

When I ask WordPress to "preview in new tab," I get a File Not Found screen. (See uploaded image.) This works fine in Chrome (which I rarely use) but not in Firefox, so I'm thinking it might be a Firefox issue. The Tablet and Mobile previews work fine, but they don't require a new tab. I thought it might have to do with pop-ups, so I made my blog's URL an exception. That didn't help. Then I disabled the pop-up blocker altogether. That didn't help either. I've never had this problem before although I've been using both Firefox and WordPress for many years. I'm working on an old laptop (current one is kaput), but I think everything's up to date. Windows 10. Any idea what the problem might be? TIA for any help. This is driving me nuts!
