There is an ongoing problem when trying to use Paypal on sites like Ebay etc. The problem is with Firefox as I can make payments using Safari with no issues. Logging into Paypal to make a payment results in a looping of the process or an error message.

I am unable to restore the previous session at the launch of the browser I already instruct in the setting to have a systematic restor of previous session, without success. It doesn't work. This is happening after having installed the latest firefox upgrade It seems that there is a problem that I am unable to resolve. Please provide with help

Why in the world did Mozilla change the keyboard shortcut for Open Link in New Window from the standard ctrl-W to ctrl-D? This's been the standard on all different applications for years and years--since time immemorial! What were they thinking?!!

(Do they hate standardization? Do they wanna make people's lives difficult?)

I'm in a multi-monitor environment with screens arranged vertically(Fig1). When Firefox is maximized on the bottom screen, a part of Firefox is displayed protruding on the top screen.(Fig2) The same reduction did not occur in Chrome.

I was converting a MS word doc on my computer to an Adobe PDF and saving it on my computer. FireFox changes it to a FireFox HTML (I'm not not even using the Browser). While MS windows 7 lets me choose which way I want to view it (with Adobe or any browser), it is IMPOSSIBLE to post onto Facebook. FB is looking for a PDF and the file I converted to is something else. So now I can't post my PDF's because FireFox intrudes into my computer and changes things. HOW CAN THIS BE RECTIFIED? Can I stop FF from doing this?

Lately (as of which version, I'm not sure), I've been noticing that if I enter a URL in the address bar of a tab that already has a page open, instead of going to the new URL I entered, Firefox will refresh the current page instead. This happens A LOT and is pretty annoying. Wondering if this happens to anyone else.

browser that used to be a good one! It automatically updated my browser and I lost all the information I had stored! This used to be a good browser! I wish I knew where some of the programmers were!

When I type anything into the Location Bar or search that is not a website address, Google search would provide me with search results. Now Bing has taken over as the default search engine and I want Google back. How do I specify Google as the default search engine for Location Bar searches? (I have already removed Bing from the Search Bar list.)

I've been trying to fix this for a week now, and nothing has worked. Everytime I try to play a 4K video on Youtube, the player stalls. Audio works, but the image just stays frozen and jumps from time to time.

I've tried every fix I could find in the Internet. But now I came here to ask for help because I tried the last thing I was avoiding (Refreshing Firefox) and after risking my custom settings, 4K videos still won't work.

Any ideas?

I'm on Mac, latest OS version, latest Firefox version. 4K videos work on other browsers

Anytime I invoke the Firefox icon and before I get to my default webpage, I get a blank screen which does nothing for a period of time. Question is how do I get rid of this situation?

Somehow, Amazon became my primary browser and I do not know how to change it to FIREFOX. SETUP says it is FIREFOX but every new tab I start wants to search via Amazon. Please help.

In SETTINGS I do not see another "option" of this "dumb" feature like Firefox has used for decades? I PREFER the SEARCH BAR as it will KEEP my SEARCH 'script' if I get a search not wanted. Then all I have to do is "modify" the SEARCH TEXT and search again. I am trying to get use to typing my SEARCH in the SEARCH bar on the FIREFOX Main screen but is getting hard to break DECADE old habits since I started using FIREFOX after I gave up on 'NAVIGATOR' a 'few' decades back? OK, I am 'ole fashioned' sometimes... I never believed in "change" for "change SAKE". AM I missing something in SETTINGS that SHOULD ALLOW us to choose the NEW WAY OR THE OLD WAY for at least awhile. I would have these issues IF I knew the way to fond, use an older PROFILE as I would still be using versions in the early 80's.

When printing a pdf from the built-in pdf viewer (pdf.js?) to a network printer, it's so slow as to be unusable. Save the same pdf and open it it in Xreader, click print, and it starts printing immediately. Size of the document seems to play a role; I knew it was slow from trying to print smaller documents in the past, but today I needed a hard copy of a 68MB pdf, and hours later, it still had not printed.

I'm running latest Linux Mint Debian Edition 4 Debbie and latest Firefox in its repositories, 78.11.0esr (64-bit). Printer is Canon imageRunner 2200, it doesn't have any other slow printing problems, as I stated above.

Problem seems to have existed for a long time...

Many directions to fix problems direct you to click the 3 bars in the upper corner and select "options". This is not there, there is nothing to select called "options". Why isn't it there? Is it called something else now? Is it somewhere else now? Is it something I need to add to that menu? Please help, it's making it impossible to enact fixes, since I can't complete the very first step!
