My ISP is Plusnet. When I try to access their website using Firefox browser I get the following error:

=====

Secure Connection Failed

An error occurred during a connection to webmail.plus.net. Cannot communicate securely with peer: no common encryption algorithm(s).

Error code: SSL_ERROR_NO_CYPHER_OVERLAP

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

I have reported the problem to Plusnet but they say 'not our problem'. Their reason being that the problem does not occur using Google Chrome.

Can you help please?

I try to access my bank website and when I log in the tab says "Something went wrong" and the page tells me Sorry, we couldn't complete your request Sign in to online banking or our mobile banking app to continue. This started on April 1, 2021 Running Firefox v87.0 (64) on Win 10. All apps are current. Tried resetting Firefox, and clearing cache which didn't work. I can sign-in using Edge. Thanks

I have three FF profiles on my Linux Mint 19.3 system (work, not-work and one for e-tail). Somehow the problem only appeared after I added that last one. All profiles have the same syntax; I checked the files. Neither one is set to be the dominant one. Typically, I don't use more than one at a time.

I also use Claws mail. Whenever I get any mail with a link I want to check out, I just used to click on that link and it opened in a new tab in the FF browser profile that was currently open. Similarly, whenever I wanted to see the HTML version of a mail, I right-clicked on the html-icon and chose open. Again, it picked the open browser.

Now, though, whenever I pick either one of those options above, I get the "Choose User Profile" box. If I pick the profile that is currently open, I get an error telling me that it's already running.

Since I mostly read email when I use the no-work FF profile, I tried to add "firefox -P NotWork -no-remote --class NotWorkProfile" but that also resulted in the choose user profile box to open.

My current work-around is to copy the link and open it in a new tab, or pull the whole mail into the tab to see the HTML version. Quite annoying.

Is there any way to get it to ignore all other profiles but the currently open one? Thank you for anyone who has an idea. Let me know if there's anything else I may add to explain the situation.

[My apologies if this isn't the right forum; I'm also attempting to ask this question in the Linux Mint and Claws forums, if those exist.]

How do I get Firefox to stop false warnings => "Potential Security Issue"? The most recent is Toastmasters.org. That website has been around for decades.

Or has Toastmasters lost control of their website?

I think the title covers it. Until recently, pressing the <Backspace> key on the keyboard would take me back to the previous webpage. Now it doesn't.

Using FF v87 in Win10 Home.

How I export my profile data from an extension? An extension I'm using isn't working properly and I'd like to export my data before reinstalling it. It's called onetab.

The menu on the top right corner is gone, so how can I export my saved data (or tabs)?

Dear Mozilla Community,

I would like to suggest you to make built in adblocker in Firefox. For example Opera have this feature so we don't need install any extension. People from Mozilla read subjects in support.mozilla.org? If not where I can send my suggestion?

P.S. I wanted to install Adblock Plus extension but I am afraid about safety so better option is to make built in adblocker to protect from malware. I think that this can be direction in good way.

Yours faithfully, Piotr

Is there a way to set a web site as my home page and not have to reset it every week or so? Also, when will we be able to choose what web site is loaded when we open a new tab?

I am Getting both "incorrect password" and "your email was returned" errors

I know the password is correct as I can still use it to log in (including logging into these forums) though I am getting this error when trying to create a recovery key or reset my password

For the "your email was returned" error, the email address is typed correctly in my account and I have gotten confirmation emails from FireFox as recently as 2 days ago. I get this error when trying to sign in to sync the Multi-Account Containers addon, as well as when trying to use "forgot password" to get a reset link.

I'm not sure how to proceed with these errors as each issue is preventing me from resolving them on my own.

At one point while I was getting the incorrect password error I got a message that my account is locked and an email would be sent to me for confirmation...though of course that also got "your email was returned"

I just got my upgrade from Firefox86 to Firefox90 working, but the tab bar is completely missing.

I still use "old-style" FIrefox. From top to bottom: File/Edit/View menu Search bar Bookmarks Toolbar Tab bar

(yes, I AM old. I've been using Firefox since Version 1 and this particular style works for me, developers be damned.)

The tab bar is completely missing. Firefox knows how many tabs I have open (it warns me when I try to exit) but doesn't show any. The area that the Tab Bar used to occupy is simply empty.

Any ideas on how to fix? (Yes, I have done the Google.)

Help. The Bookmarks were always shone on a left sidebar for my ready access. But all of a sudden today, they are gone and I can't get them back.

How do get my Bookmarks into a left side bar???

There is so much to read that does not apply. I get lost looking.

Help Please! I 've recently upgraded from Win 7 to Win 10 and one of the many annoyances is that I can't "email a link" any longer from Firefox. I have searched the web & followed all the instructions but the "use Gmail" option is simply absent from the dropdown choices in Options/Applications/Mailto Please, please how can I get the "use gmail" option. Many Thanks

Over the last week or so I have been unable to receive my CenturyLink email through Mozilla Foxfire. I am having to use Chrome to receive & send my emails... Help anyone?!

The absolute weirdest problem. If I'm on the Brita website (brita.com) and type in another url to navigate away, I press enter, and it just refreshes the same page I was on. This happens across the brita.com domain, regardless of what url I type in, even if I type the full url (including https://www.), and if I click a search or url suggestion in the dropdown, even in a private window, anything. This has never happened to me with any other website.

Obviously I can just close the tab and open another, but this is strange enough I figured I'd see if anyone could figure it out (or at least replicate my experience). I would appreciate any insights!

I am trying to have some of more important add-ons visible but I cannot seem to accomplish that. The solutions provided in FF's forums did not yield results. Are there any solutions?

Attached are screenshots of how I have my preferences set-up.

web pages don't display but address is shown at tabs, can't see options but other menu options seem to be okay. I uninstalled and erased all related data (I could find) multiple times and reinstalled multiple times but problem remains. I tried refresh, safe mode, etc. At installation I get error VCRUNTIME140_1.dll not found, a susequent installation finishes without errors. I am sending this from another system because I can't use the problem unit for this post. The problem system is similar to this one. I am puzzled and seek help.

EMAIL DISPLAY IN GMAIL: Hello. All of my emails open the first page okay, but an increasing number of action pages in emails do not open. Those pages contain forms to fill out, petitions to sign, and donations to make. This problem began in late February/early March (FF 86&87).

The tech support at EveryAction.com said she thought they need Javascript to open, but I couldn't find any setting or add-on in FF to enable/disable Javascript. I don't know why all of their action pages have been opening fine for years--maybe it's related to FF's new versions. I tried adding Policy Control because it supposedly enables/disables Javascript but it didn't solve my problem.

The tech support at Earth Justice wrote this in response to my report about their action pages not displaying: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:87.0) Gecko/20100101 Firefox/87.0; https://earthjustice.org/action/investigate-troubling-payments-that-threaten-the-florida-panther?contactdata=8D8RgJTCUXwiDCjeWPHh7wQ1fwDy7YSqjRoUFBMLj9iH2tXUofJiQ1CKU%2fIhkHfdjY8KsFkiYme4BhD4yp%2bpJ9S13ALo6NdUs4CtwLA2KaAhIZ0GP2%2bWq9ZUYNwtkHNEKC%2bxUF4VNRJ1XirXG00WayYuwLGnnHVzRWtCwf3s%2fqtR64TlcMwKx0w2e3AyPLspJ8xDw1TQNs%2fSBpWztf%2fNBkvDKFTrC6fsKAvY54zt13IfVVPcfU%2byEdneTMzDaYIN&ms=email&utm_source=crm&utm_medium=email&utm_term=action&utm_campaign=2102_Action_Panthers_Haaland&%3butm_content=HTMLTakeActionButton1&emci=5a0f473e-c881-eb11-85aa-00155d43c992&emdi=01870d6d-d68b-eb11-85aa-00155d43c992&ceid=962627 "We are still investigating this problem, but it appears to be concentrated among Firefox users. We do know that our EveryAction forms require Javascript to be enabled, so if it’s disabled and you’re able to enable it that might work and would be helpful to our efforts to sort this out. Let us know if you’re able to get that to work, and thank you for your patience."

I would be very grateful for your help in solving this problem. I'm sure there are other users out there with same problem. Thank you. --Sincerely, Bo Bergstrom.

Recently, I had to uninstall and reinstall Firefox. When I clicked on the address/search box, I used to see a line like "search with" followed by a list of my alternative search engines; now, when I click on the box, I see the "search with" heading, but no search engine icons. How do I get them back?
