After restarting my computer, I got a new FF web page and ALL my bookmarks as well as history have been deleted.

How do I get them ALL back?

I have tried every solution on the Mozilla Help section - I cant do a Restore I have a very old version of backups - 2016

The online help system is going around and around in circles not giving any solutions. 4 hours of trying to sort this out is ridculous.

I really do not want to have to move to Chrome, I far prefer Mozilla, but I can not afford to loose more time sorting this problem out. If not resolved here, I will reluctantly have to restart all my bookmarks in Chrome.

I need all my bookmarks - some are work related.

Please Help

The "comment" sections on various news sites (WSJ, Politico, WaPo, etc.) are always flaky for me under Firefox. The symptom is clicking the comments button/link does nothing- the comments do not show on the web page.

I have tried the Make-A-New-Profile trick and the Clear Cache/Cookies thing- which seems to work most of the time but then after a few days it's back again.

This is getting really frustrating. I have both Edge and Chrome browsers installed and they work 100%. I've read here that it may be caused by a corrupt cookie or cache (hence the new profile trick) but if that's really the problem how do the other browsers get around this?

Any help or suggestions would be much appreciated.

I have been using Firefox as my default application to open PDF files and everything worked correctly until recently. Now when I open a PDF, the file opens a blank browser tab and continues to open more blank tabs until I close Firefox to stop more tabs from opening.

I have restarted Firefox in safe mode and get the same results.

What can I do to fix this?

Ever since Outlook did an update, it will not function in Firefox on my laptop. I can log in and see the list of emails but can not view emails in the reading pane nor delete an email. I can move between folders but not that is about it. It works fine on my computer at work but not here at home. It also works when I open it in a different browser like Explorer. I have cleared my cookies, cleared the cache and even restarted in safe mode with the add-ons disabled and it has not solved the problem. Just wondering what else I can do. Would like to continue to use Firefox but don't want to have to use two browsers just to accommodate Outlook.

Please help.

Pictures/clipart from websites are suddenly being saved as jfif instead of jpg. There seems to be no alternatives available when choosing "save image as..." Problem does not occur with Chrome. How do address this issue in Firefox?

I hate it how I have to first click on the "View history, saved bookmarks, and more" button in the top right, and then mouse over to bookmarks on the menu, and then click on bookmarks just to access them. Is there any way to set up a shortcut to the main bookmark menu? I went into customize and placed the "Bookmark Menu" button to on, but that only shows bookmark options on one click, not all my bookmarks.

I was attempting to load the site "https://masterbuilt.com/" in FFQ 61.0.1 64 but the page stays blank. I do have adblock and it's disabled for the site. the address bar shows a green secure icon for the page. it will load in IE tho. I'm stumped.

there were hundreds of bookmarks for duckduckgo, but have successfully deleted them. Still have hundreds of bookmarks of another site that I can't delete, one by one or wholly. http://lawfulvlegal.com/ you can scroll for 20 seconds and they are still there. Don't know how this started....have used the Microsoft malicious software removal tool but nothing came up.

I'm fine with multiple tabs and all that, but sometimes I want to keep things in the same tab. But then some web developers don't seem to understand this, and code their pages to force links to open in a new tab (or possibly even a new window, but at least I have that under control). There used to be a perfectly cromulent extension that solved this problem by adding an "open in same tab" option to the context menu, but it has not been updated for FF Quantum and probably never will be. Are there any current extensions that do this? Or is there another way that I can restore this option, and only open new tabs when *I* choose to do so?

Username and Passwords are already saved. When I select a username from the drop-down list, automatically the password associated with that username is entered. When I click enter or login, everytime and for every account it says - Invalid Username. When I enter the username and password manually, only then I am able to login. Uninstalled and re-installed Firefox. Cleared History, Cookies, Cache but the issue is still there.

Hello, I am from Hellas (Greece) and I have installed an English-Greek dictionary, these two languages are 100% non conflicting since we have different alphabet thus the dictionary automatically spell checks both languages at once.

I used to have this dictionary default and it worked perfectly until a recent update keeps changing the spelling dictionary to the default, which is the local language -> just Greek.

If I change the spelling dictionary it will work until I restart mozilla (or sometimes until I restart the pc). This is kinda irritating at worst, not a big issue, but having to change my selected dictionary every time is ridiculous.

See the attached image to understand what Mozilla does by default.

The solution is given below but I'll write it here:

1) Go to about:config (hit I accept the risk there)

2) Right click on a blank area

3) Select: New->String

4) Name that new string as: spellchecker.dictionary

5) Set the value of it the name of the spell checker, in my case it is: English & Greek

6) You are done!

To see the name of the string you need, simply install a dictionary you want, go to a page that you can write something (lets say facebook) and right click, select "spell checking" and then scroll to see the dictionary options you have, the name of your dictionary is the one you see in that little drop down menu like in the image I provided.

When Browsing Firefox just freezes for ~7-10 seconds and goes unresponsive, this happens especially often when watching youtube videos in the Background, opening a new tab or closing a tab. This happens close to every 10 minutes and it is really annoying, I have tried a lot of the things i read on here, for example:

generate a new places.sqlite, disable Hardware Accelleration, I have both Refreshed Firefox and Re-Installed it. I have updated my Graphics Card Driver. I have done a Windows Disk Cleanup. I have Reinstalled Adobe Flash. I made sure to Disable Proxys

With the upgrade to FF 61, I finally got Fox News Channel streaming to work on FF. I have streamed Netflix on FF for years. Now I have to watch Netflix on Microsoft Edge. These continuing video issues with FF are getting tiresome. I get error code F7121-1331-P7 Solutions anyone?

I've got the same problem as Firefoxfan1 since upgrading to the v60 as Firefoxfan1. When i want to open FF it won't open 2 times out of 3 and when it never opens or else FF crashes or i have to end the tasks in Task Manager. Once FF opens without hanging i click on a URL shortcut, the tab hangs. It won’t open. I try opening one or more new tabs, they all hang, except 1 out of about 5 which opens correctly. Sometimes opening new tabs hangs indifinetly until FF crashes. My FF/crash reports/pending folder holds a great amount of crashes, every crash produces 3 dumps. 0861bfdb-4ff5-417f-aa4a-1ba7ac97989c.extra 0861bfdb-4ff5-417f-aa4a-1ba7ac97989c.dmp 0861bfdb-4ff5-417f-aa4a-1ba7ac97989c-browser.dmp Unlike Firefoxfan1 i never experienced this type of problem, i’ve been using FF since the end of Netscape back in the 90’s. I’ve already sent these dumps to FF as recommended. I uninstalled FF and reinstalled but the problem persists. I also reinitialised FF to no prevail. Any hints on what the problem is ?

After an Adobe flash update this seems to have wiped out all my favorites! After I reboot my computer I got the message "update available". I downloaded the adobe installer and installed the thing. I have two versions of firefox: FF 61.01and FF_esr 52.8.1. For some reason it opened the ESR version, that doesn't normaly happen. After the FF reboot all my favorites from both browsers were gone. The session was normaly restored. ?? I doubt it's a virus. This is the normal procedure for flash updates and my firewall asked permission to access *.macromedia.com.

Firefox browser has defaulted to "searchitnow" as the home page and default search engine, which was not wanted, appeared to come with a Java update, has also impacted Chrome. Help getting rid of it appreciated.

I have seen reports that the next update will turn on DNS over HTTPS and Trusted Recursive Resolver via Cloudfair by default. I want to be sure I know how to turn this off before I will install any further updates to Firefox, I trust MY DNS more than Cloudfair.

FF will not save my password for at least one site. The issue is not related to the site. All other Browsers are able to save the user and name and password to this site.

I am using FF 61.0.1. I have noticed that "Ask to save logins and passwords for websites" is greyed out. I have FF set to remember history. I have already read about how some people who has this problem in earlier versions were able to fix the problem by not using Private Browsing (which I am not) and by launching FF as an Administrator, which also doesn't take care of my problem.

I have even imported the saved logins from Chrome where this works, and even that did not address the issue. If someone can tell me what is causing this to be greyed out, I think that will be the answer to the problem.
