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.

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

Hi all,

I'm having a repeat of this issue: https://support.mozilla.org/en-US/questions/1291551

Again some links from emails have been giving me the "Warning: Potential Security Risk Ahead" page with the error message "SSL_ERROR_BAD_CERT_DOMAIN". I get this in safe mode but not in private browsing. I have tried all of the fixes suggested last time I asked about this problem including deleting cert9.db but that hasn't worked this time (so maybe it wasn't the fix last time either).

To be explicit, I've tried all fixes on these pages so please don't suggest them again without providing an explanation about why you think it will work (a technical explanation please): https://support.mozilla.org/en-US/kb/troubleshoot-SEC_ERROR_UNKNOWN_ISSUER https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can https://support.mozilla.org/en-US/kb/firefox-and-other-browsers-cant-load-websites https://support.mozilla.org/en-US/kb/secure-connection-failed-error-message https://support.mozilla.org/en-US/kb/connection-untrusted-error-message http://kb.mozillazine.org/Error_loading_websites https://support.mozilla.org/en-US/kb/what-does-your-connection-is-not-secure-mean https://support.mozilla.org/en-US/kb/websites-dont-load-troubleshoot-and-fix-errors

Good Day. Connection to the official French Tax website https://cfspart.impots.gouv.fr (French IRS-equivalent) is not authorized on my browser (Firefox 78.10.0esr / MacBookPro OSX 10.11.6) although this browser version is said to be supported by the governmental Tax website.

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?
