Firefox 86.0.1 (64-bit) Linux Mint 20.1 Cinnamon

Dell Printer 1355cnw

Using the 3 line Menu top right when you try to print using Dell 1355cnw unfortunately after a series of beeps it reports in the window:

No Suitable Paper 024-969 Printer load Paper then press (tick) Custom 0x0 mm

There is nothing wrong with the paper

I can print without problems to the same printer from Google Chrome. I've even installed Opera that also works perfectly without problems. Firefox is my favourite browser, don't want to desert. Could somebody please help. Many thanks Keith

Hello, I would like to know is it possible to see/check the history of synced devices on Firefox. In other words, is it possible to check whether somebody synced my Firefox with theirs without me knowing it or being aware that happening. In this specific case I know it happened 100% and I just need somehow to prove it ... Thank you!

Since somewhere last autumn, when I download any file from any website, the browser vanishes without any warning on the moment I navigate to the destination folder.

I maintain 2 websites (Joomla), and last week both required uploading a few files in Phoca Download to make them available to members. Now also on this upload the browser was completely gone when I navigated to the folder where I kept the fles.

I use Firefox since about 1995. I looked in about:Crash (first time ever), there were to reports, both unsubmitted: 69990c58-1a5c-40a3-9141-666607416103 6/22/2020, 1:23 AM e6f0688e-73e4-4c19-8e0a-01ec3c28e996 2/22/2019, 4:09 PM I have submitted them both now.

Hey,

on one of my notebooks (Thinkpad E495) FF occasionally crashes. This started happening a few months ago. Before I've been using FF on the same machine for years without any issues. It's pretty random but usually happens at least once a day, usually shortly after startup or wakeup from hibernate mode. A while ago it used to even crash back to back twice in a row meaning after I reopened it, it immediately closed again and only worked after I selected to restore the previous session after the 2nd reopen. Nothing is registered under about:crashes and I don't see any errors in the system event log.

I already tried to disable hardware acceleration and reinstalled FF completely without any addons besides a different adblocker. I cannot really reproduce the crash in safe-mode but don't really want to browse the web for possibly hours without an adblocker.

Any ideas what this could be or what else I could try? Maybe downgrade to a previous version?

How can we clear / delete our data from Firefox installed on a device we don't use any more remotely. Just by removing the device from Firefox account will not clear the login and password information from the browser in the old device.

So i have old Bookmarks.

very old.

The Bookmarks file dated 2014. What version the Firefox was that generated that files i do not know.

If i import those .json files there are none Bookmarks imported.....

The new shiny fancy format is json packed with lz4. Can i deactivate this? I do not want compression! Bookmarks are text, text can be packed, but no not in modern times. Modern Times require speed not space. Or in other words: I want the bookmarks seachable with my editor.... I have space for a few TB for bookmarks.

Hello, I am a screenreader user and since updating to Firefox 86.0.1 (64-bit) I have encountered a serious bug on Netflix that is very easy to reproduce, even for those who don't normally use screenreaders. Serious in the sense of making the site unusable once it hits. It happens with both the screenreaders I use, Windows Narrator and Non-Visual Desktop Access (NVDA).

Basically on Netflix if you do something to cause an informational alert (such as adding a film to your list), then this alert is read out over and over, indefinitely. You then can't hear anything else such as a plot synopsis, or if you move to a different button, you won't hear information about what button it is, as the screenreader just keeps re-stating the same alert. The looped alert keeps playing even after you start watching a film or show. As I say, the site becomes unusable. Whereas in older versions of FF such alerts would be read just once and that was it.

To reproduce: Start a screenreader (the built-in Windows Narrator can be toggled on and off with ctrl+win+enter). Go to the Netflix website (you may need an account and to be logged in). Pick any film or series tile, and do something like press the 'add or remove the item from your list' button. Or press it's 'rate thumbs up / down' button.

You will now hear something along the lines of 'alert: item was added to your list' repeated over and over.

Another example is to start watching a show with a skippable intro (such as Homeland for example). You will hear 'alert: press the S key to skip the intro' repeatedly.

As I say above, in older FF such alerts were read out just once.

So, is this a known issue? Thanks for reading.

Hi, Dear Support

Thank you for your browser, it's pleasure to work with mozilla firefox

So I've been experiencing a rather annoying bug/issue, and I have a work around for it, but I would love if anyone could help me figure out the issue at hand. I couldn't find a relevant, up to date solution for this issue.

Basically, certain websites (the most notable being Reddit) will eventually no longer load. In fact, it won't even try to load. I will click a link from a Google search, or even just type in the URL for Reddit directly, and Firefox just does nothing. No error, no loading, nothing. The tab will stay blank with the URL listed as the name of the tab. I can't seem to tell if other browsers have this issue as it requires a bit of use/time to pass, but it doesn't seem to be an issue in Explorer. It isn't JUST Reddit, but it's only a couple of sites that this occurs on.

I do have a workaround --- if I tell Firefox to "Forget This Website" - suddenly it will work again. I will be logged out and see the default page due to having deleted all saved dated - but the site will work (for maybe a day) before I have to forget it again.

If this was a once a month type issue it wouldn't be a big deal, but the fact that I have to constantly re-do my local settings because of this is frustrating.

I am running Windows 10 and my Firefox version is 85.0 (64-bit). I have tried disabling any add-ons such as my AdBlocker, however that does not fix the issue.

Hi,

I think I broke the ALT keyup events in some way, probably with my configuration but not sure how.

If I put this code in the console : `document.addEventListener("keyup", e=>console.log('alt: '+e.altKey+' | '+String.fromCharCode(e.which).toLowerCase()));` and the press the keys, I have the following results:

- pressing "I", I get the expected "alt: false | i" - pressing "ALT+I", I get "alt: true | �"

I do not have the problem with other modifier keys like CTRL

hello there and good evening:3 my husband and i are having this repetitive and extremely frequent bright yellow pop up with a robot that states "a webpage might be slowing down your browser." then the option to wait, or stop it. i've ran out of patience with this notification to the point to where even though i'de hate to, i would have no choice but to switch back to chrome just to stop being spammed by this pop up while im trying to relax. it happens more frequently on youtube and walmart.com, and i just want it to stop because it seems as if when it does show up, once it starts it never stops, and it actually slows down my webpage to the point of becoming unresponsive and stalling/crashing my only webpage open at the time. my husband has the same issue and we both use windows desktop. it only started appearing after the latest update. please, can someone help me make this thing go away? its very stressful and i cant browse in peace anymore on firefox. yes we have turned off all background processes, and we both have scowered settings troubleshooting for hours at a time to no avail, it just never stops and it behaving like a really bad bug.

I hope someone can help me with this problem. I own the domain "cpaaffiliatesnetwork.com" and the site serves as my business site and access to my business network platform. The site is SSL secured and the SSL certificate was renewed in February 2021 for 1 year. Since the SSL renewal, I started having issues accessing the site from any browsers installed on this computer (Edge, Firefox & Chrome). I have now managed to fix the display issue in both Edge & Chrome through clearing cache / history, BUT, I have tried the same with FF with no success. I have also tried uninstalling and reinstalling Firefox, but, still receive the error below for any attempt to access the site: Secure Connection Failed

An error occurred during a connection to www.cpaaffiliatesnetwork.com. Peer’s Certificate has been revoked.

Error code: SEC_ERROR_REVOKED_CERTIFICATE

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

All external people i have asked to check the site have confirmed it works fine for them, but, it will not work for me. Hoping someone has a suggestion many thanks in advance :)

Hello,

My computer crashed and my windows profile is gone.

I made new profile and now my firefox profile and bookmarks are missing Typed about:profiles but don't see anything but the one I'm using now

-Erkki

Firefox 87.0 (64-bit) on Ubuntu 20.10 is currently unusable as it won't open anything.

• Firefox opens with no page loaded.
• Clicking the single "getting started" bookmark does nothing.
• Entering a search term in the address bar and pressing 'enter' changes the url in the address bar but nothing is loaded and the page remains blank. There is no indication that anything is loading.
• Entering a url, such as "www.youtube.com", and pressing "enter" does nothing. There is no indication that anything is loading.
• Opening the menu by clicking on the burger icon, then on "preferences" does nothing except make the menu disappear (same with most of the options in the menu).

In the browser console I see some errors and no request info (see screenshot).

I've tried `sudo apt purge firefox` then installing again, which didn't help. The problem started with ubuntu 20.04 (I only updated to 20.10 to see if it might resolve this problem).

I've tried the "refresh firefox" option, starting in safe mode, and clearing the startup cache, which didn't help.

Any suggestions would be much appreciated.

Sir/Ma'am,

My system is a standard install, and when I open Firefox, click Help, About Firefox, and then click the linked word (Mozilla) "Firefox is designed by Mozilla" it takes me to "www firefox com cn" ?

Is the version of Firefox in the Linux repositories the China version with an American facelift?

I know you all do not have command and control of this, but I thought someone should be aware that the default Firefox browser for Linux installs seems to be the CCP Firefox and not American version. With all the CISA activity, it might be something to look into.

On old tabs, where I have opened google.com, there is infinite captcha! Once I solve it, it will immediately return back. I tried delete cache and cookies and restart PC. Nothing helped! I read on reddit it is known issue with Firefox!

After a recent upgrade...I got an error message about an 85/86 discrepancy. I was told to delete and restore Firefox....Now I can't load Firefox because of a 7-Zip error "Can not create temp folder file." Please help.
