Firefox Community Forum

The email address box does not accept the email address and comes up with an error message. The only way to send an email is to use a different browser ie Google. Emails are still received as normal on Firefox / BT mail

Home Internet speed via cable 500 Mbps. When checking the Internet speed through the Firefox browser (version 133.0.3), incoming and outgoing about 250 Mbps. That is, the browser cuts the speed twice. When checking the speed through Google Chrome (version 145.0.7632.160), the Internet speed is about the declared 500 Mbps. Please help solve the problem with Internet speed through the Firefox browser.

I'm reposting a question already opened here because a moderator suggested to do so. Actually I though I was posting to the international forum from the URL...

I was trying to access a local HTTPS website of an embedded device (a Siemens S7-1500 PLC) that is using a self-signed certificate, but was unable to go on (attached image #1, in Italian language) due to the the SEC_ERROR_REUSED_ISSUER_AND_SERIAL error. I've browsed a similar PLC webserver in the past, so the fact that the device exposes a similar certificate serial number is not so strange for me, considering also it's self-signed.

The problem is that I cannot follow the instructions of the Mozilla knowledgebase here because I'm not able to identify the correct certificate of the website!

In the attached image #2 you can see that the connection is detected as not encrypted, I suppose because only the form part of the HTML that is posting the data using HTTPS while the rest is using HTTP, but I'm not sure. If I click on the padlock icon (attached image #3) the info about the current certificate is not displayed.

Then I went into Tools > Options and searched for "certificates"; as you can see in the attached images #4 and #5, neither in the Servers tab nor in the Authorities tab I can find any item that is related to 192.168.10.2 (the webserver IP address) or Siemens (the embedded device manufacturer). But unfortunately the error persist! Initially there was a 192.168.10.2:443 line in the Servers tab and I removed it and restarted Firefox, but it didn't solve, so at the moment the situation is the one depicted by the attachments.

I had to use Microsoft Edge to access the website, but I would like to solve this issue and use Firefox instead. Is there anything else I can do to bypass the error? Why doesn't the error page provide a way to correctly identify the wrong certificate using its fingerprint and/or name? Or, maybe, is there a way to disable this check for local IP addresses or for items in a whitelist?

Thanks for your help.

I am having the problem a fix was created for previously where attempts to sign in to my google account continually redirect to a request to clear cache and cookies. Have done so multiple times, still can't log in. Can log in on Chrome so definitely a Firefox-specific issue.

We have resolved an issue with Google prompting users to ‘clear cookies and site data’ when logging in. A fix has been published, via Firefox remote settings that does not require a Firefox upgrade. Users will receive the update over the next 6hrs, if you would like to update immediately simply restart Firefox.

Note: The issue was related to CHIPS being enabled in Fx131, this feature has been temporarily disabled while we resolve the issues. Users who have disabled 'Allow Firefox to install and run studies' in Privacy & Security settings will need to enable to receive the update.

I bought Mozilla VPN a month ago, and nothing has turned up.

How do I get a refund of my money?

Then I can buy StartPage VPN.

Firefox is really going downhill.

It's very tricky the clone a FF profile, so I want to avoid that. (If there is a SIMPLE way to clone a FF profile, that would suffice. I have found no such animal.)

I would like to start Firefox by invoking different UserChrome.CSS files.

Is that possible?

I am not intereted in RUNNING both these simultaneously.

yes, I realize I could go through renaming and unrenaming files before starting FF to achieve this. But, I am I'm looking for a method using native FF resources.

My browser was recently updated to 150.0.2, and on the new launch page after update describing new features, it prompted me that the new free mozilla vpn was available to try. When I clicked on the link to follow the steps to set it up, it said to click the vpn icon in the toolbar, but I don't see that icon there. When I go to more tools -> customize toolbar to try to find that icon to add it back, it doesn't appear among the toolbar options. Is this something I still don't have access to because it's in a limited beta, or is there some other way I should be accessing this?

Ok, I screwed up.

I was trying to solve a problem I've been having with regular releases of Firefox and it occurred to me try the ESR release so I downloaded and installed it. The good news is that it solved my problem, the bad news is that I just barrelled into it without thinking, assuming that my logins and bookmarks would just transfer over like with regular releases. They did not. It turns out I should have made a backup of those things first and I can't open the old regular release of Firefox to properly back-up those things now. Oops.

I've been reading lots of forum posts here and elsewhere trying to get those files into ESR and I haven't been successful. From the profile manager I've located the profile that still contains that info and I've tried:

Copying and pasting the "logins.json" and "key4.db" files from the "default-release" profile into the ESR profile which didn't work.

From "about:profiles" I also tried to "launch profile in a new browser" of the default-release profile so I can open that profile and properly back-up bookmarks and logins but I get a prompt to create a new profile which I tried several times and only resulted in several profiles of the ESR release.

Then it occurred to me that If I could just delete all instances of ESR and open the old default-profile then I could back-up the logins and bookmarks, THEN download and install ESR again and import those files but before diving into that I need to make sure that won't loose my original default-release profile info.

So experts, does that sound reasonable? Delete all instances of ESR so I can open the regular Firefox? What's the best way of going about that?

Thank you.

I only use Firefox to play two browser games that both use the 1-5 keys as an alternative to clicking the mouse. Accidentally clicking Ctrl and switching tabs out of nowhere is becoming a really annoying problem, but I don't see any way to just turn off shortcuts and hotkeys like other the other browsers I use. Is there any way to do this? Even a specific extension that makes the Crtl button do nothing would help, the one I was recommended won't download due to a "corruption".

In Firefox 152.0.5 under Windows 10, when I hover the mouse pointer over a tab, a balloon pops up showing the text that is on the tab. I find this extremely annoying as I can read what is on the tab. I have searched on the Mozilla site, and I have searched with Google, all to no avail. How can I disable those redundant popup balloons?

I'm using a Windows/Linux client called WSL (Windows Subsystem for Linux). I've installed Debian as my WSL OS and for a long time I had Debian version 10. Firefox worked fine with ver 10 but this morning I upgraded to Debian version 13 (which required me to upgrade to the latest version of Firefox).

Firefox still launches okay but I wanted to change my home page to Google. So I clicked the 3 lines at the top RHS which showed me a popup menu but none of the options was selectable. Eventually I twigged that to change settings I needed to launch Firefox using sudo.

I managed to change the home page okay but I then realised that if I launch Firefox without using sudo, my new home page is ignored. Conversely (if I launch using sudo again) Firefox launches at a tiny size and can't be re-sized (at least, not using my mouse cursor). I've attached a small screenshot.

All I can do is to display it full screen and then I can tell that the home page is indeed now Google. I don't remember having these problems previously so can anyone give me a clue as to what I'm doing wrong??

I encountered an issue where pasting multiple images causes the upload to fail. It seems like it cannot handle more than 2 pictures at once. Could you please help me fix this?

Hello

We use ManageEngine's ServiceDesk plus and all has been fine until Firefox 148 update was installed.

The body of a request where we type details of a case or insert images now will not display anything. The data fields are fine, it is just the description box which appears to be iframe. Other browsers still work, but we prefer FF.

Thanks in advance - Terry

Let's say I have a group of 5 tabs. If I open a new tab from any of those tabs, I want that new tab to end up at the right of the group but not part of it.

Can I do that?

Hello,

Is it possible to hide the green "New" label next to new features, such as the current "Add Split View" example? There should be an option for the label to be automatically removed once the feature has been used at least once.

Thank you and best regards, Martin
