Firefox Support Forum

Hello:

I have 2 profiles in use. 1 for personal use with their respective bookmarks, passwords, and extensions, and I have no trouble syncing with this one. However; profile 2 that is for work use that has its respective bookmarks, passwords and extensions, has become a nightmare.

It happens that I have both profiles on the same computer and when trying to create an account in Firefox, the system asks me to enter the email registered in profile 1, with the warning that bookmarks, passwords and extensions will be mixed.

I mention that I have migrated from Google Chorme to Firefox for speed reasons and because I use windows 7 (I don't like later versions) Now well; in Google Chrome you could create as many sessions as were registered but in Firefox you can't.

Oh! I have been working fine with Firefox but suddenly an error occurs (it has happened to me 2 times in the last 2 months) in which the program closes and all the data of my profiles stored on the pc DISAPPEARS or is deleted (including cache), when I want to open them again:

firefox.exe -P

Then I have to give myself the task of synchronizing profile 1, but profile 2 I have to be importing from my previous Google account or importing a backup Bookmark.

The option to copy and paste the data from Firefox to replace it in the path (supposedly brings with it the data of everything):

C:\ProgramData\Mozilla-1de4eec8-1241-4177-a864-e594e8d1fb38\updates\308046B0AF4A39CB

with Firefox turned off it has not worked for me. Since when opening I see 2 profiles called Default "X" and Default "Z" without data.

This is a headache that if it happens to me, it happens to millions who have 2 or more profiles.

Why can't I sync a second profile? Why do you insist that there can only be one sync per device? Is there a solution for this?

Note: I have read all the tutorials out there and the situation remains the same. Synchronization with 2 or more profiles is never described.

Thank you very much to whoever asked this question!

I had installed FF version 78 ESR in a newly formatted SSD back in 2020. At that time, two profiles were created automatically under the Profiles folder: xxxxxxx.default, and xxxxxxx.default-esr. The first profile, the one without the "esr" suffix was never used - I don't even know how to switch into it.

The non-esr profile folder had always contained only 6 files totaling about 70 KB. The contents never changed - until a few days ago.

A few days ago I noticed the non-esr profile folder was modified. It now contains 28 files totaling 125 MB. 26 of the 28 files were modified on the same day (May 23rd), at 2 different time points. That folder and contents haven't changed since then.

I continue to use FF using the esr profile without apparent problems, but I would really like to know how/why the non-esr profile got modified suddenly. Any ideas, anybody?

Since I updated to version 113.0.2 every time I try to open certain websites, Firefox shows an error message "SEC_ERROR_UNKNOWN_ISSUER". Once I choose to accept the risk and continue it redirects to the IP address "79.137.248.81" that redirects to spam. This happens on multiple sites, certain popular sites such as google work perfectly.

Yesterday I uninstalled and installed the browser. I rkilled and scanned my system with Malwarebytes, Avast and HitmanPro. I also have no malicious addons I found. Nothing worked.

I am attaching pictures of how the error shows.

Please Help.

I installed Firefox at work and set my personal email address as secondary to my business address. Well, I liked Firefox so much that I decided to use it at work and at home - and I removed my personal email from my business account. Unfortunately Firefox is still recognizing my personal email as the secondary address for my business account and I am completely incapable of making a new account. My bookmarks and saved passwords are all different between home and work. I NEED two individual accounts, just like how I was using my browsers with Chrome. t

Dear Anyone

You'll laugh like drains. I've got PagePlus 9 which lets you design .PDFs with fillable fields in, the idea BEING I could send out a form which anyone could fill in in their browser without having to understand word-processing. Looked great in PagePlus 9, loaded it into Firefox and it sucked royally - fields and data all over the show. Back to the drawing board. Nearly 5 hours and countless revisions later, it still sucked royally in Firefox.

Then I tried it in Chrome, Edge, Hola and CCBrowser and it worked like an absolute dream. Displayed perfectly. Let you enter data perfectly. Put it back into Firefox and it immediately sucked blue whales through thin straws again. So it's GOT to be a hewge bug with Firefox and .PDFs. Anyone know what it is and how to handle it?

In retrospect, I, too, find it Pretty Darned Funny that I didn't think of testing it in another browser before spending 5 hours on the thing! But if it's a Firefox and PDF bug, why's nobody spotted it in Developerland? That's the bit I don't get really. (If they HAD, surely they'd've just opened up the inner workings of another browser, learned what they were doing wrong and used what they'd learned?)

Can reload it and take screenshots if requested.

In the last month Firefox using google search simply refuses to search, this is becoming annoying to the point where I will start using other browsers. Is there a fix for this?

Error: "Secure Connection Failed

An error occurred during a connection to accounts.firefox.com. 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."

When it happens: - Irregular frequence. The same websites once work once don't. They work with Chrom/Edge/From my mobile(same wifi/router). - Sometimes I have to refresh the page a few times - Happens for all sort of webistes. From local news, to GitHub/Youtube/Google/Any website

Steps I have taken: - Cleared cache/cookies - Reset PC/Firefox - Cleared all extensions - Deleted Firefox (And manually deleted all folders in AppData related to Firefox) and reinstalled afterwards

Nothing helped. Any idea what is going on? I checked Mozilla documentation for SSL issues, but it didn't help either

I have a task bar at the bottom of my screen -- or I used to. Ever since I installed a Norton protection program several says ago, the task bar shows up sometimes and other times, it is gone and I cannot access it. When it's there, it gives me access to the websites I'm using, all my written files and picture, video and other files, volume control and other options. I NEED TO SEE AND USE THIS TASK BAR ALL THE TIME, NOT SOME OF THE TIME WHEN FOR SOME REASON IT'S THERE. AGAIN, I WANT TO ACCESS THIS TASK BAR ALWAYS WHEN I'M ONLINE.

FIX THIS.

Thank you.

I am currently unable to view any file activity or ownership information in Google Drive in a shared folder. I have tried the following troubleshooting steps:

• Quit and reopen firefox
• Relaunched firefox in safe mode/extensions disabled
• Cleared cookies
• Tried in other browsers (works in Librewolf, Brave and Chromium; doesn't work in any Firefox browser (Nightly, beta, standard)

In my MS Windows 11 system in control panel, Apps > Default apps. Firefox is listed twice. In both of these there are these two separate listings: ".htm" and ".html". Below both these listing it says: "Firefox" "Firefox HTML Document"

Question: Can I remove/delete/uninstall one of these Firefox's? Question: Should I remove/delete the ".htm" and just leave the ".html"?

Hope this makes sense. Thank you for your help.

My old iMac's Firefox browser was automatically changed to ESR (by Firefox) since the computer could no longer update the operating system through Apple (obsolete). When I purchased a new iMac and migrated my data to the new computer, Firefox ESR is still the browser, and says it is up to date. I am assuming I should get the most current regular Firefox version, but don't know if there is an easy way to change the version and preserve all my saved passwords, logins, bookmarks, etc. Looking for guidance. Thanks

I'm amazed, just AMAZED I can't find the answer to this with a simple google search, or searching the questions here, and I re-worded my search several times. All the answers I could find, even chatGPT (I know it's not alway sup to date) told me to use this option even though I specifically told it it wasn't there, is anyone aware that sometimes the option isn't there? What gives? Not blaming anyone specifically, but this a really simple question, I'm I the first person it's ever happened to?

I'm trying to fix a sound problem where videos will not play, and this is a suggested step. The sound on youtube videos plays with Google Chrome, so it's not my sound drivers, just with firefox it doesn't play. One of the steps as well was the clear my info, I cleared everything except history, I wished there was a way to back those up, I'll look it up.

Starting firefox in safe mode doesn't fix the problem either.
