I have working "firefox developer" with "firefox-dev" profile. I want to migrate to stable "firefox", but release firefox show message

You've launched an older version of Firefox

Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox.

so what can i do to migrate? is it possible to migrate to profile with lower firefox version?

No suggested fix works. Reinstalling does not help, toggling DRM application does not help. It was obviously the update (at least for users on 78.10.0esr with OS X 10.9.5) that did it. Is there some way to get this registered as a bug?

There's a website I visit that firefox caches for some reason in such a way that it can't be updated anymore when the page changes. I know that the developers of the site won't fix it, so I need a way to fix it on my end. I have to Ctrl F5 to refresh the page otherwise it will say "Posted 1 second ago" permanently and never show any comments or upvotes or anything.

I was hoping there was a way to disable the cache for a specific website only. There is a way in Chrome, but I don't want Chrome.

Alpha overlays appear to have screen corruption on some sites

This question relates to my use of Firefox 88 on MacOS 10.14.6 on a dual-GPU retina MacBook Pro (15-inch, 2018). I'm using a dual external monitor set-up, and still running 10.14 due to 32-bit compatibility issues with some of my (scientific, bespoke) software.

I am pretty sure that there is a very odd, browser-level bug in alpha display on my system that leads to, for example, the overlay of YouTube's UI appearing peppered with row-wise stripes of other colours; or PDF page previews not displaying properly. There is nothing relevant displayed in either the (JS) console log; `dmesg` or MacOS's Console.app application. The appearance of the stripes / corruption is randomly different each time: it is different in private browsing mode to not, for example, and refreshing the page alters their exact appearance.

I have done the obvious things of disabling hardware acceleration -- no change -- trying in a new private window with no extensions / addons loaded -- no difference -- but I do not necessarily want to nuke everything and try again. This problem has existed for as long as I have used FF on this computer, but I am just reporting it now. Mostly it's fine, aside from one variety of captcha that I cannot solve!

I have no idea how to go about debugging this and alas I don't have the time to do it "properly" -- I am on a system with SIP disabled and can easily load up FF in lldb, for example, if someone could give me targeted advice. I am not a web developer and do not know the exact api call that causes this -- but it appears to be used in pdf.js' sidebar page overlay code, but not the actual page itself. Most PNGs, SVGs etc are fine.

Please see the attached series of screenshots – if it's not clear what I've done (the same youtube video in and out of private browsing mode with no extensions, a PDF viewer; and that page reloaded showing a different pattern), please don't hesitate to ask -- the corruption is pretty visible in all cases, I think. The fact that I can screenshot this and share it with you means, I think, that it is not an OS-level graphics driver bug and is probably a rendering bug.

Thanks for your help, and sorry if this is the wrong forum!

Hello,

since the latest update I experience problems with printing. In my store we print hundreds of little slips every day, they are the size of 1/3 of A4 format.

The webapp which prints them generates an A4 PDF, where only the top 1/3rd of the page is actually filled with information. Usually we print this via systems dialog, we have it set to print on Letter DL format, change the orientation 90 degrees and zoom to 270%, which gives us a perfect result.

As of yesterdays update, Firefox somehow changed the alignment rules, and the zoomed-in page now gets centred instead of aligned left, which completely breaks our process.

Is there any way to force left alignment? This is affecting two different machines exactly on the day of the update rollout. Changelog only says the print margins have been changed but I believe also the alignment has been affected by that.

Thx

Per title and attached image.

Why do I no longer have the option to view image in the same tab any more? I should not need a browser extension to have brought it back. This new feature is, frankly, rather annoying and I would like to have the option to have it back. Please don't tell me to modify userChrome.css because that doesn't seem to do anything anymore. I have tried on numerous occasions to use it to get rid of the obnoxious Email Image by following markup examples given on numerous forums, so I don't trust it to bring back a feature unjustly stripped from me.

Or, failing that, tell me how to get that context to open in the background. I have that option set for links, and am rather unhappy that it is ignored on this new image context and bookmarks to a lesser extent.

It has been a day since updating to this new version, and I hate it already.

I just installed Firefox (88.0) on a brand new Surface Pro, signed in to my Firefox Account, which gets me my stuff synced over, such as the Grammarly, LastPass and Pushbullet extensions. I log into those respective applications as needed. I start browsing.

Now, when I open either of those extensions from the menu bar, they open their little in-place window. If I now touch anything in these windows, about 80% of the time the following happens:

  • The little in-place window closes
  • Firefox becomes unresponsive (menus, other controls, web pages, close window)
  • This lasts for 60 seconds (reliably)

However:

  • If the extension is visible on the menu bar: problem happens
  • If the extension is tucked away in ">>" (More tools...): no problem (this is also a decent-ish workaround)

Given that this affects multiple extensions, I'd expect this to be a Firefox issue. Also, I have no idea how to troubleshoot this (I have not been able to find logs).

Things I tried to no avail:

  • Refresh (through installer)
  • Cleaned out profile manually
  • Tried extensions before logging them in

Thank you for your help.

Someone could be trying to impersonate the site and you should not continue. Websites prove their identity via certificates. Firefox does not trust cfspart.impots.gouv.fr because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates.

I'm developing an add-on for Firefox which will take the colors from the favicon of the current tab to color bits of the tab-bar dynamically.

I'm having trouble finding out how I can modify browser CSS, for example in the Browser Tool box console, this works perfectly fine: ```const activeTab = document.querySelector('.tabbrowser-tab[selected="true"] .tab-background'); activeTab.style.background = "rgb(0, 221, 255)";```

but when inputting this same code in my add-on, it cannot query that same selector (I've given it tabs and theme permissions). This also does not work as a stylesheet.

Can anyone point me to what I need to access the browser UI DOM?

Hi Team

We have a problem with printouts, i.e. when we have a generated printout and it is opened by the built-in pdf viewer in ff, then after clicking print, the spooler becomes clogged and the pdf file weighs almost 100 Mb. There are no such problems when opening the file with the installed Acrobar Reader DC application. A request for information on what may be the cause of this condition. I would like to add that this is the VDA VMware Horizon version 7.10. The Mozilla Firefox browser in the picture is 78.0.2 esr 64 bit.
