My download library window used to display files well over a year old, everything I have saved since the last time I deleted all browser history. Recently, everything older than six months was no longer displayed. The files are still there, I just have to search for them. Now it no longer shows anything older than 4 months. "Show all history" does not work. Is there a way to restore that list?

I have multiple Bookmark folders. I want to export (and then import) just ONE of the folders to another computer.

When I go through the EXPORT BOOKMARKS TO HTML process the html document created contains ALL 18 FOLDERS even though at the time of creating the document, at the bottom of the export menu page in the "NAME" slot it showed just the name of the folder I wanted to export.

As far as I know there is no way to edit the html document to delete the unwanted folders. If there is, please share the information.

Thank you for your assistance.

It's so frustrating that the keyboard shortcut for closing tabs is right beside the one to quit Firefox. I've lost countless hours because of this, and it's so easy to accidentally do. Is there a way to keep this from happening? A simple "Are you sure" confirmation dialog would be great, or I really like the Chrome "hold command-Q" to exit feature. This seemingly simple function is proving extremely difficult to accomplish.

Yes, I'm aware of session restore, but (1) It does not preserve my window arrangement. I use multiple desktops for various tasks, and they each have related browser windows. (2) I need to see webpages exactly as they were when I opened them. Sessions expire, dynamic pages are refreshed, content is removed etc. That is all lost.

I do not want to disable session restore completely. It can still be useful. But, I do not want to trigger session restore automatically every time. Manual activation is ideal.

regarding: "browser.tabs.warnOnClose" I do not want a warning for closing multiple tabs. I often have many windows open and that warning gets annoying. It also doesn't prevent me from accidentally quitting when I only have one tab open.

I tried setting browser.warnOnQuit to true, but it's ignored.

I simply want a confirmation when I use the keyboard shortcut to QUIT. That's it. No side effects. Can Firefox do this?

The first time I noticed the Megabar (I believe it was FF75) I absolutely hated everything about it and ruins the experience using Firefox. I am also not alone in this matter because as soon as the change was established, communities popped within hours to fix the problem. The old way of fixing this eyesore of an issue was the old about:config and changing around the settings then VIOLA! back to normal. Now after the update to 77, the Megabar is back and forced down everyone's throat and the old about:config is no longer the fix to this terrible experience. Literally after an hour of this trashbar being up, videos and guides popped up to try to fix it. Whole communities have been formed to hate this feature and ask Firefox to change it, or at least make it optional to go back. My question is, looking through google has only come up with the chrome.css(?) fix to this mess. Is there any way to change it back to the old url bar without having to go through the chrome.css fix or just uninstalling and reinstalling a previous Firefox or do I have to just migrate to another browser like Opera or Chromium?

I do not use the majority of keyboard controls in Firefox-- only Ctrl+F. Lately, I've noticed that using Ctrl+I in editor windows also pops up the Page Info window, which I have never used on purpose and am perfectly comfortable accessing via Firefox's menubar.

I have been searching for over an hour, and every Firefox add-on that I can find to fix this problem has been removed.

Ideally, I would like to be able to configure all of my keyboard shortcuts, but practically I will settle for being able to disable Ctrl-B, Ctrl-I, and Ctrl-U.

Does anybody knows why firefox sometimes restores to a previous session, like the one atleast a couple weeks ago, instead of the one I had when I closed it for the last time? and if I can do something about it, I tried using the files from sessionstore backup but they just update to the new session

I set winRegisterApplicationRestart to false. Firefox doesn't appear in the task manager startup programs list. There is no link to firefox in the startup folder. Nevertheless, firefox runs itself when I log on. How can I make it stop?

I'm on Mac. When I open a PDF in Firefox I get a print button and a download button. The download button does not offer a Save As option. It simply uses the name used in the browser - often this is a number or day or some other appellation that is less useful than allowing me to rename the PDF myself. Chrome offer to rename the file before saving but I hate Chrome.

Maybe I'm overlooking something?

Hey, I'm using the restore previous session feature. Its really helpful, but I assume since the last update it is not working properly. Whenever I use the private firefox browser (window) parallel to the normal one (window) and close the normal browser before the private one, my last active session of the normal browser is not restored.

When I close the private firefox window before the normal firefox browser window everything works fine with restoring the tabs.

Any way around? And please fix this annoying bug. Thanks!

I searched this forum but couldn't find an answer. I have "restore last session" turned on, but I'd like Firefox wouldn't reopen my last visited site after I close the browser by closing the last tab. In other words: if I close the browser by a regular means (by clicking the rightmost upper X, or by right-clicking the taskbar and choosing close window) it goes to the last viewed site when I reopen the browser – and that's ok – but when I close the last tab and the browser closes, I don't want to see this site again when I reopen Firefox. Is there a way to achieve this? By the way, this is the standard behavior in Google Chrome.

On multiple websites I visit, picture in picture happens automatically when I scroll past a video or click another section of a page. I find it highly annoying and distracting. I would like to disable it completely. How do I do this? I'd appreciate an answer that isn't too technical. Thanks.

I go to the Firefox Configuration Editor (about:config page), find the signon.management.page.fileImport.enabled preference and toggle it to true. But I still don't see the entry: Import from a File…

Can someone help me? Thank you

Hi Guys and Girls,

For the love of all that is keeping me alive at the moment please help solving the issue of spell checker not working.

I have a new MacBook Pro and setup Firfox by installing it and siging in to sync.

The spell checker does not underline the words as I type here or in Google or WhatsApp Web.

Also when I right click no language opion appears.

I does work in Gmail for some weird reason.

After follwing a suggestion of installing an add-on dictionary and resarting Firefox, no change came about.

See attached for more...

Thanks in advance for your help.

Yahoo intruded and functions as default search, even though Google has been and is still designated as default in the settings. I removed Yahoo from the list of 1-click browsers, but that didn't affect its unwanted function as default search. This began out of the blue several days ago, and I have no idea how. I dislike Yahoo in general and have not been on that site. I'm getting really frustrated!

For quite some time now I've had keyword.enabled set to false in my about:config because I don't like having the address bar try to autocomplete or turn things into search, when I do a ctrl-l.

I do like that I am still able to use ctrl-k to do a search when I need to. This would place a ? at the start of the field and whatever I type gets sent to search.

In a recent upgrade, ctrl-k still places the ? at the start of the address bar but doesn't send things to search. Instead, it now behaves as if I did a ctrl-l and typed in a bad URL.

I'm on Firefox 80 (on Fedora 32) but I can't be exactly sure which upgrade brought this change in behavior.

Is there a way to get the old behavior back? ctrl-l to enter a URL, ctrl-k to search.

I use Send Tab to Device all the time. To my phone, my tablet, my work & home laptops. Except recently, the tab I send won't show up on my phone. Notifications are enabled. I can send from my phone to my work laptop. I can send from my work to home laptop. But to the phone, it says sent, and nothing ever arrives. Everything is synced. What else can I do?

I run a blog on WordPress and while editing a blog post I tried to "justify" the paragraph but it did not work. I previously used chrome in which it worked, but in Firefox it seems that its is not working.

It's a simple question: Why Firefox enforces by default extensions like Amazon, Bing, eBay, Google ? What really these extensions do?

Paradox#1: Firefox enforces to use those totally insecurity and unreliable companies! Paradox #2: Firefox don't even show those extensions mentioned above! Paradox #3: Even when I remove them from "Options->Search Engines" these ones keep being enabled and hidden! Paradox #4: Third party program needed to manage those Firefox hidden extensions! I Disable all above extensions by "CCleaner" and: Paradox #5: they comes back by default in every Firefox damn update!

I wish I'm wrong I would pleased if someone explain in an article, or even in few words, why all those. I think Mozilla should detailed explain.

Thanks in advance and Sorry for my English.

hey I used Firefox in my previous Windows, and even though the sync section of my account was active, I can not recover the data now. Is there a way to solve this problem?
