Firefox Support Forum

I got an error on one of my open or pinned tabs (do not recall which it was). I do not recall what the error was and did not screenshot it because I was sure that closing Firefox and restarting it would fix the issue. I did just that, closed Firefox and reopened it to find that ALL of my pinned and open tabs were GONE. This also happens if another instance of Firefox is opened and I close my main one first by accident and then close the other Firefox instance - ALL TABS LOST.

This is what I have done: • I started to restore the pinned tabs as I could remember what they were but I was not able to remember the open tabs that were not pinned • I searched for lost tabs on the web and on the Mozilla support site but was not able to find any useful help - most of it seems outdated or no long compatible with my version of Firefox. • I looked for the sessionrestore files on my local PC but could not find them - this must have changed in some version of Firefox between version 42 and version 82 that I have. • I looked in the AddOn store to find something that would help restore and prevent this issue - but found nothing. A very old post, from 2012, indicated one that did this but it is no longer available. • All of the Options in Firefox to restore previous session, reopen previous tabs and all that were blank.

This is VERY frustrating in that it results in lots of down time to recreate what was open and is equivalent to working on a document for days or weeks only to find out that the Microsoft file got corrupt or did not save properly.

I am using Firefox version 82.0.2 (64-bit).

Two questions: 1/ Is there any way I can get the pinned and open tabs back from the previous session? 2/ What can I do to avoid this issue EVER happening again.

Thanks!!!!

For past few days browser fails to go into full screen mode properly. Tabs and url input section remain in sight. Screen mode is toggled with F11 or via menu bar, zoom. Previously it was working?

When I visit sites and try to save JPGs to my system, often times the saved image is not readable on my system by any other apps except Firefox. I tried renaming them to png to see if that would change things, but no. The latest batch of images I saved that exhibit this behavior is from aliexpress.com Some sites (unrelated?) only offer webp images to be saved so I usually have to use a different browser to force the images to jpg instead. The images on aliexpress are still identifying as jpg so I don't think the webp issue as rearing here.

Tried signing in to firefox sync and account got locked with the following message, "The confirmation email we sent to <my email-id>@gmail.com was returned and we’ve locked your account to protect your Firefox data."

My email works fine and I could use it to login and ask this question. Please help

Hi all

I am running firefox 82.0.2 and I cannot export my bookmarks to html

When I take the jon file and check it on another browser many bookmarks are missing like a lot

Is there a tool I can use that will export my bookmark -- so the job gets done and I will remove my current version of firefox

Thank you all

No matter what I tried, I can not delete my browser history, nor can I delete single websites from my history. The history list works fine, all visited sites are visible and browser history is updated, but I can not delete any of the entries or the whole list. I have uninstalled and reinstalled Firefox, but the problem is still the same. I have read and write permissions on the .mozille folder, so this can not be the problem.

I have started getting alerts from Norton 360 regarding "malicious browser extension activity 4" from a website called https://tribedone.org. I have no idea what the website is (I can't reach it) but the alert is showing very often and Norton requires a shutdown each time it detects and repairs the issue. Any suggestions please?

Hello dear Mozilla community!

I've faced an issue with search engines configuration for Firefox on macOS. I'm doing the following:

1. Removing all but one One-Click Search Engines, leaving only one engine in the list (currently my preference is DuckDuckGo): https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2020-11-17-04-32-41-395a2a.png or https://imgur.com/DKqvzZ9
2. When I type search request in the address bar I'm seeing nice and clean search suggestions from Search Provider of my choice: https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2020-11-17-04-32-13-a8d46c.png or https://imgur.com/a/slivHlF
3. Close Firefox
4. (not sure what other conditions needed)
5. Open Firefox
6. When typing search request in the address bar I see that Amazon and Ebay options are back and a suggestion line "This time, search with ..." as added by firefox: https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2020-11-17-04-32-02-4a25db.png or https://imgur.com/vjq0NCf
7. In the preference I see that those two searches (Ebay and Amazon) were automatically re-added to One-Click Search Engines: https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2020-11-17-04-32-23-91dd1d.png or https://imgur.com/ibnlzLS

That issue is happening to me across different versions of firefox and isn't new. I've been seeing it for a few month hoping that to resolve in a newer versions. But as of right now I'm on 82.0.3 (64-bit) and the issue is still there.

It's a bit annoying as I have to my preferences literally every time I need to restart Firefox (which is especially annoying to do right after restarting FF to switch to a newer version).

Any suggestions and help is welcome!

Best regards, Serhii.

This problem occurred Oct 24, 2020 Australian Eastern Daylight Savings Time (3 weeks after daylight savings time came into effect here). The operating system time is correct. I have cleared the cache several times, rebooted and shut down overnight.

A forum site is displaying the correct times. A site displaying weather information uses the correct time; I loaded it just after 3am and the first time it displayed was 6am as expected.

1. A TV guide normally highlights in red programs currently showing; at present it shows programs showing one hour previously. In Google-Chrome no programs are highlighted. I have removed the cookies and that has made no difference. 2. Facebook.com times are one hour late, both the time of posts in the newsfeed and times of notifications.

Ever since I downloaded Firefox, I have been having an issue where when i click on a link from a search engine, it automatically opens the link in a new tab. I've looked around in the settings menu, but I couldn't find any way to alter it. The closest option would be to open link in new window, but I just want to open the link in the tab that I am currently in. I have tried going into about:config although I couldn't find any setting that successfully fixed the issue. Any help you can provide is greatly appreciated!

Thanks! - T

I need help restoring my passwords. I saw a suggestion to refresh Firefox, and so I did, thinking it wasn't more than disabling the add-ons. I didn't realize it would eliminate my logins and passwords. Can someone help me find them? Otherwise I'm in some trouble.

Hello! I also have a problem with mozilla! The account is always disconnected when I restart the MAC. And I always have to log in to my mozilla account. What can I do to stop being delegated? Thanks!

I had accidentally refreshed my Firefox, and after adding back all my old data, I found that the pocket stories were missing form my new tab. I manged to fix this issue, but when I go into new tab settings to make it show more than 3 stories, there are no options for them. It just gives me options for search, top sites, highlights, and snippets. How do I get these settings back?

So, I accidentally clicked a link that takes me to a site I have never logged into. Firefox prompts me with 3 userids. One is more or less a throwaway, but two are for sites I want to be secure.

I have disabled the form history in options. I have selected each item and tried either delete or shift-delete. None of these options work.

The site continues to present me with 3 userid options.

I hope this is not a major security threat since I am the only user on this computer and the site is one I have never visited, but it worries me nonetheless that I cannot remove the Firefox suggestions.

How do I change, or is there a way to stop the browser from going back a page when i press delete too many times on a box or I haven't managed to click where I thought I had?

I am receiving too often the message "A Page is Slowing Down Your Browser, What Would You Like To Do?" It becomes annoying. I tried the same site with Edge and it responded faster. What can I do other than switch browsers?

Hi all, I have an Apache site on Kubuntu 20.04 with a certificate signed by my private CA. I've added the root CA ceritificate in Firefox and in Chromium.

Firefox throws a SEC_ERROR_BAD_SIGNATURE error

Chromium accept the certificate as valid

What can I do?

Notes: the site url is "https://hdev.h.net" (with an internal IP address inside my lab)

Attached there are:

- the authority settings page
- the certification authority certificate as seen by Firefox
- the site certificate

Firefox version 82.0 Ubuntu Chromium version 86.0.4240.11

I use Firefox 82.0.2 (64-Bit) on Windows 10 and Foxit Reader 10.0.1.35811 for reading PDF files. In the FF settings I set the handling of PDF documents to "Open with Foxit Reader 10.0". Once I have done that and click on a PDF file I will be asked what to do with the PDF and I confirm again to open it with Foxit.

That usually works for the moment but FF will always forget this setting again. I have configured FF to use Foxit at least five times over the last days days. But the next day FF will just download the PDF file again and do nothing with it (not even ask me what to do with it).

Any help is much appreciated.

Since about a week or so ago late October or early November 2020, Gmail will not load in Firefox.

I began having this problem about a week ago. Sometime in October or early November of 2020. Gmail will not load in Firefox. Clearing cookies and all cache, works one time. Then it starts all over. Resting also works, just once. This is a giant PITA. I have to reset or clear the cache every time I use Firefox or Gmail won't load. It works fine on all other browsers. If I want to use Firefox for Gmail, I have to reset it or clear it every time I start Firefox. I have to go back to Chrome to use my Gmail.
