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. Error code: SEC_ERROR_UNKNOWN_ISSUER

Can anyone help on this one ? Thanks a lot in advance best

Hi All,

Fedora 33 firefox-87.0-12.fc33.x86_64

What happened to

--> Tools

   --> Web Development
     --> Network

I really need this functionality back!

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?

My Firefox Developer Edition crashed. The menu disappeared all of a sudden and I can't get to any websites now. I tried removing everything FF related on my Macbook Pro and then downloading again and it still looks like the screen shot included here. Nothing going on at the top anymore and it looks like it's 'applying update' but this never ends.

Any ideas what might be the cause of this? And what I can try to fix it?

This seemed to all happen at the same time I was working on a GoDaddy managed WordPress website - while pushing my staging site to the production site. GoDaddy said their system software was being updated but that shouldn't affect a browser.

Thank you for any info you can give!

When I open a first Firefox instance from taskbar in Windows 10, if I do a Google search then right click on any of the results, then select "Open Link in New Tab", FF lalways opens that link in a new window, not a new tab as requested. The new window takes up the right hand half of my display which means I have to manually size it larger or maximize it. This behavior continues as long as I use the first FF window to open any links - they never open in a tab of the original window and only create lots of windows - this is very hard to deal with IMHO. Now here's the weird part - If I use one of the new windows, then FF behaves just as it should. Do a Google search and all links can be opened in new tabs in the new window, as requested. I did not notice this strange behavior until about April 10 when I believe I accepted a new update to FF.

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.

For years I've been right clicking on memes and GIFs, selecting "copy image location," and pasting it in a forum on a website. I know there are other ways of accomplishing this but losing the ease factor of "copy image location" is AWFUL. In retrospect, the simplicity of it was breathtaking. Does anyone know the possibility of its return in an update?

one of my google accounts, which I have been able to sign in through firefox for years, suddenly started giving me an error message after entering my email address on the google sign in page. I have another google account and I'm able to sign i using firefox just fine. The error message given is:

This browser or app may not be secure. Learn more Try using a different browser. If you’re already using a supported browser, you can refresh your screen and try again to sign in.

I'm using a windows 7 box and Firefox 85.0.2.

I'm able to sign in just fine when I use google chrome. I've cleared cache and data in the browser. I'm not sure what else to try. Any suggestions? Any other information I can provide to help identify the problem?

Unfortunately my main desktop computer decided it no longer wants to boot up. I was using Firefox as my browser and would like to know if there is some way I can get all my bookmarks back. I have a second desktop computer and was wondering if I opened a Firefox account on that computer and then signed in with the same email and password, would I be able to see all my bookmarks or am I simply out of luck?

Thank you for your help--Matt

Every time I try to download attachments, the original email closes and I am returned to the inbox. Not so much of a problem if I am working from the inbox, but an absolute pain when I am working from sub-folders.

How can I stop this?

Thanks,

Shaun.

Answer the question "How can I create hotkeys/ special abbreviations for autocompleting full words & phrases for repetitive text (NOT for autofill on forms which I understand), ie email addresses in FF, etc.?

Apologies if this has a tech name I am not familiar with.

I am an old fart (76) and had firefox reasonably set up and nor this tired old brain must remember how it was and how to jump through the hoops that the juveniles thought as better... Give me a break !! the complaint I had which I found a workaround was to DELETE up to 1G of cookies so I had a little usable ram and space on my HDD... Some of the cookies were HUGE... My OS has been Linux mint or other flavours of Linux since about 1990 and used to boot in less than 20 seconds, then it would load the previous days applications where I left off in another 10 seconds... Now, judging by the sixes of the files downloaded to refresh Firefox you are writing BLOATWARE WTF... Why do you think I would not touch Intel & windoze? DAZE of compulsory Amerikan speling & corporate spying are numbered if this keeps deteriorating... 20,000 cookies a day? and how big is the file to install firefox... That is what I call BLOATWARE...

I watch informative YT but when it gets boringly repetitive I just scan what is force fed in the vain hope I will spot something of interest... 90% is crap, or dumb'ed down BS to find a few paste jewels...

My brain is somewhat addled with Dementia, and afflicted with aspects of Asperger's Syndrome, Bi polar disorder... Give me a break Please...

I have firefox sync set up because I have to reset my computer sometimes, for personal reasons. However, upon logging into your firefox account to sync the data, it requires a code from the email account. BUT, the password to my email account is on the firefox account I'm trying to sign into, meaning I can't sign into my email to get the code to sign into firefox. I had to make a new account (the one I'm using now) in order to ask a question about it. Please help as soon as possible.

Pandora is not playing on firefox 88 64 bit cleared cookies and cache made pandora and exception on FF and my virus software restarted computer plays just fine in chrome

Miro.com is an online collaborative whiteboard. When using the mouse, the scroll wheel is used by the site to zoom in/out of the whiteboard. As of Firefox 88, the speed at which zoom occurs on this website when using the mouse wheel is much faster than in previous releases of Firefox, causing the zoom steps to be much too large too fast. This has made it difficult to use this site.

Note that I'm not talking about Firefox magnification zoom, but about how Firefox is passing mouse wheel information to the Miro.com website for use in their whiteboard zoom feature.

Other users on the Miro community board are reporting they fixed this issue by reverting to Firefox 87:

I have been a fan of the awesomebar for quite some time; tab selection using % enables progress after chaotic web surfing and bookmark searching using * circumvents the need of retracing already known websites. (I have removed suggestions and history though, I find that those are mostly in the way.)

One limitation for me as a programmer is that while searching for Python helps me find the correct bookmarks, including C in a search is not helpful, as a c anywhere in a bookmark will give a hit. This even goes for '.com'! The same problem occurs when searching for bookmarks in the bookmark library.

My suggested improvement would be to allow search terms to be interpreted narrowly. This could be done by adding quotes, for example "C" (single quotes could also work).

Is this already possible in some way? And if not, where would be the best place to suggest the improvement? [feedback page reads "Please check back soon"] ( and I'm not sure whether this suits the Bugzilla platform.

After Firefox update, secure connection failed error on all sites when using a vpn (Private internet access). Turning the VPN off allows all sites to load. What is going on?
