Hi all,

After month of using, the screenshot function of Firefox seems to have disappeared. Right click contextual menu does now show the option to take a screenshot and the [three dots] -> Take Screenshot menu action does nothing. Moreover, the icon of the function seems to be missing (see attached images). I run latest (83 64-bit) version on a new MacBook pro.

Thanks in advance, Alex

In the last week I've continually had the error message PR_END_OF_FILE_ERROR appearing in place of various websites. There's no consistency - one day a website can load fine, the next I get the error message, the next day it'll load fine again. And the problem seems to be getting worse... It's driving me mad! Please help!

How can I sign up for Mozilla (firefox) forum?

I have an account, but won't recognize my credentials. They ARE correct.

I try to set up a new account and the security question "how many letters in Mozilla" doesn't work. The answer is 7, but says it's wrong. WFT?

I tried three different ways, 10 times, to clear the "Cached Web Content" not matter what I do (6.0KB) remains?

Can someone please help me out here? I cleared and cleared, restarted the machine... I cannot get rid of the (6.0K)?

I'm using a 5 day old new MacBook Pro (16-inch, 2019), running MacOS Big Sur 11.0.1, using FireFox 83.0 (64-bit)

it's frustrating and I don't want anything stuck in my cache that might be tracking me, following me around.

Cannot create Certificate Exception

On my home network, I run a Ubiquiti UniFi Network (Security Gateway, Switch and WiFi Access Points). I access the administrative functions with UniFi Controller software which accesses those functions via https://localhost:8443. The Gateway Roouter itself is at 10.0.0.1:443, but cannot be administered at this address.

When I try to access the website, I get the standard Firefox invalid security certificate warning as the certificate is self-signed (image 1). Once I Accept the Risk and Continue, I can successfully log into the site. But once I quit my Firefox session, whenever I launch Firefox and try to access the site, I am again given the same invalid security certificate.

Previously, I was able to create a certificate exception which bypassed that warning, but no longer.

When I go into Firefox's Preferences : Privacy & Security : Certificates : View Certificates page, I can see a Temporary exception (image 2), which presumably only lasts for the current session. I try to Add Exception, enter my localhost port number' (image 3), then click on Get Certificate. It tells me that I have valid, verified identification. There is no need to add an exception (image 4).

And yet, every time I visit the localhost website, I am prompted with the warning. Any ideas of what I might do avoid this warning every time I want to access it? Is there some way to allow this device (or even ALL devices) on my home network to be trusted?

Also attached are images of my UniFi Certificate.

Thank you for any assistance.

I am unable to get the 'recommended by Pocket' panel to appear in new tabs with my normal user Firefox profile (Firefox account sign-in) on Mac Catalina. When I go to about:preferences#home the option simply is not present.

I created a new user login on my mac to access banking and other financials. This uses a separate Firefox profile (including new Firefox account sign-in and email), and the 'recomended by Pocket' panel is present.

The panel is present on new tabs opened for my normal Firefox account sign-in on my iOS (iPhone) Firefox install.

The about:config settings searching for 'pocket' appear to be the defaults, and match the settings in the financials account.

I have tried in 'safe mode' (add-ons disabled) and have done a Firefox 'refresh', however my add-ons (and presumably everything else) were restored when I signed back into my normal Firefox user account.

Hovering over the Pocket icon in the address bar displays 'save to Pocket', implying to me that it has signed me into Pocket. I've signed in at getpocket.com. New Firefox profiles without signing in do not show 'recommended by Pocket' in either new tabs or the about:preferences#home configuration page, but I expect the functionality requires being signed in to a Firefox account.

Help or suggestions much appreciated.

For the last week or so, I've been having an issue with media not playing properly on websites. Specifically, when I read webpages which have embedded Twitter images or videos, I see the message "The Media Could Not Be Played" where a screenshot of the media used to appear. There is a blue "Reload" button, and when I click it, I can briefly see the screenshot for a split second before "The Media Could Not Be Played" re-appears.

With YouTube videos, they fail to play and I get the message "An error occurred. Please try again later". This happens with both embedded videos on webpages, and directly on the YouTube website itself.

All of this media works properly when I open the same pages in another browser like Chrome. I would prefer not to switch browsers. Is there a way to fix this error?

Suddenly tabs won't close & hitting "Command" & a link opens a new window instead of a new tab. Anyone know how to make tabs close & also how to revert to allowing "command" + clicking a link to open in a new tab & not a new window? I've tried shift + re-opening Firefox & I tried 'safe mode' & it's still happening.

Hello,

I have been having weird problems with my Firefox since I tried getting back to using it. I have reset everything before using it again. I changed the language back to English but the hamburger icon list is in Japanese. A minor issue but I can manage.

But this one is really annoying. I click on a link and it closes it down for me in 1 second. Here's a short clip of what I'm referring to.

Hi:

I located the following instructions for sorting bookmarks: "Click Bookmarks and then click the Show All Bookmarks bar at the bottom. Right-clickHold down the Ctrl key while you click on the folder you want to sort, then select Sort By Name. The bookmarks in that folder will be sorted alphabetically.".

I followed them, got to sort but nothing happened regardless how many times I tried. Is this supposed to work on an Apple?

Thanks.

I have a new MacBook Pro 2020 with MacOS Big Sur 11.0.1. I have made Firefox the default browser by going to the Apple menu and choosing System Preferences then choosing General. I have also made Firefox the default browser by going to the Firefox menu and choosing Preferences then General. On that screen it says that Firefox is not my default browser and there is a box to click on that says "Make Default". I click on it then click on "use Firefox", but when I click on links in my email Safari still opens. Any suggestions.

I often need to print or download pdf presentation files from online sources which I used to do on Safari (I use imac) On Safari, the pdf presentation automatically rotates on the print page, so then I can use "save as PDF" on portrait and everything looks good. (then I just rotate the file to landscape on Preview or PDFexpert to read the presentation).

When I try to do the same on Firefox, on the print page, the presentation does not rotate and remain landscape. The problem is, when I choose landscape to print, then the presentation is not centered on the page and skewed to one side so I get much wider margin on one side.

Is there a way to fix this issue?

I appreciate any advice or input!

Hi! For several days I've been unable to check notifications and click emoticons on FB. I just spoke with a tech who checked other browsers (Chrome, Safari) as well as my phone and I was able to do both with them all. But I still can't in Firefox. I've checked to make sure I'm updated, and I am. So she suggested I reach out to you. Should I try uninstalling Firefox and re-installing? I'm assuming I'll lose my history? Thank you!

Okay I just uploaded the new version of firefox I think 83, and every time I restart my computer or anything like that I have to re-log back into EVERYTHING. All my google accounts everything that require a password. It has for the most part my passwords saved but it i a huge hassle especially since I work from home it eats up a lot of time.

It doesn't save my tabs I had left open either. I can get them back when I go to sync tabs but I have to do it one at a time. It literally takes me back to the "Important News: Changes to your Firefox" page every time and its been days and its super frustrating. If I have to do this every time I will have to switch over to chrome which would be a bummer. I have tried fixing it in my preferences section of firefox and made sure everything is lining up there so it should be saving my info but no matter what I do it just takes me back to that page along with my ad blocker and honey page as if it was my first time signing in

Please help I can't do this every time I log in

Since the update, I'm unable to access ANY protected directories on any sites (those where a small modal dialog box appears at the top of the page asking for a uid/pwd pair and displaying the name of the realm above that). The dialog box doesn't even appear, the page does not change from its previous location, and the "I'm thinking" animation in the tab continues forever without ever seeing an error message.

Any suggestions? Must I downgrade? (uck)
