Firefox Support Forum

As of a few days ago whenever I start Firefox the window appears with the Bookmarks sidebar panel already opened. I click the "X" on the sidebar and it will close - until the next time I start Firefox. If I choose Menu->View->Sidebar->Bookmarks and uncheck it the panel will close - until the next time I start Firefox. No matter how the Bookmarks sidebar is closed, it will always reappear when Firefox is restarted. Even if I switch to some other sidebar, Bookmarks will replace it on startup.

I've searched about:config and found no setting which seems to control sidebar behavior on startup.

I assume this is the result of some recent update. Is there no longer a way to permanently disable the Bookmarks sidebar?

MacOS 12.7.5 Firefox 127.0 (64-bit)

I have the same question as the OP in this post from a few years ago: [https://support.mozilla.org/en-US/que.../1265898#answer-1241526].

I am currently finding that the address bar history search using caret "^", does not always list all the webpages that I have visited, especially if I found the page using the search bar within the site. Is there a way to enable Form and Search History in the most recent versions of Firefox as described in the previous post?

Hi, i have formatted my macbook pro, before i have made a back up with timemachine. I'd like to restore my bookmarks but i can't find it on the back up. I have tried to find on Library>Application support but in this folder there is not the Firefox folder in wich i expected to find the Profile folder.

I installed Firefox on a Macbook Pro with Apple Silicon, M3. The installation was from the Firefox site, I downloaded the dmg and then dragged into Applications.

I find that playback of media stutters, and is choppy--not sure of a better way to explain it. E.g., YouTube videos and the Bandcamp player have "stuttered sound". Opening another site in another tab can make this effect worse. Likewise, trying to run Google Meet in a browser window causes basically everything on the computer to become very slow.

This still happens even if I go to "about:profiles" and then "restart with add-ons disabled".

But if I switch to another browser, Safari or Chrome, then I don't have the issue. e.g. I can play YouTube in the background fine even when running some compute intensive task.

I have also tried turning on/off "performance settings" and the "use hardware acceleration" checkbox underneath it -- neither of those seem to have any effect.

Activity Monitor showed that at most Firefox was using ~4 GB of memory of a total 48 GB, and the memory pressure indicator seems to be quite low.

I have run Firefox on other systems (e.g. System76, older Macbook Pro) with multiple windows open each having 20-30 tabs and never had an issue like this.

It really seems like it has something to do with how Firefox is interacting with the M3? Happy to learn I'm wrong. And happy to provide more details about the hardware or my settings if it would help.

I have saved a lot of shortcuts bookmark on my homepage,yesterday when i opened my firefox,it was all gone and it went back to default homepage. what do i do to recover it.

Sometime in the last few months, Firefox (Developer Edition) stopped allowing redirects and links to file://-protocol URLs. Is there a way to re-enable this for my personal browser, e.g. via about:config or the like?

Thanks!

After years, I changed my default browser to Firefox instead of Safari. However, in spite of my careful searching and attempts to solve my problem(s) with preferences and reading help FAQs, I am unable to resolve the main issues. I am unable to go to LinkedIn, either my own page or anything else in Firefox. It goes to the page and remains stuck trying to log in. I can copy the url address and paste it into my Safari browser bar and all proceeds as it should ad I get logged in, etc. There is also an issue with my NYT digital account. Sometimes Firefox acts normally, signing me in and allowing me to read articles and so forth. But often, capriciously I would say since it makes no sense at all it will arrive at the lage and for an instant I'll see the article, or video, and then the page will go blank. Reloading produces the same result and I am unable in Firefox to see the content. If I go to the content on Safari, all is fine. I am seriously considering returning to Safari as my default browser. What is going on here? Thank you.

I'm on a new Mac Studio, but also found that it had started to not show notifications on the older iMac.

The password I've been using to access my stored payment methods is suddenly not working. I've tried using my Master (sorry, Primary) password and this doesn't work either

For two days will tab crash for TikTok. For years, will not allow access to certain sites and no contest entries for the last few months. Worked before. No phone help and to download the browser doesn't work. I was upset as won't load TIktok and I NEED IT as use it daily. Please fix it ASAP!! I wasted time contacting Monzilla, as was only link for Firefox. They told me no help wasted today.

Are Firefox extensions sandboxed from the rest of the operating system? Suppose I have installed a malicious extension/add-on on my system. Would it be possible for the extension to access and tamper with my operating system? I do not care if it tampers with the browser tabs or data inside the browser as long as it does not have a way to tamper with my OS. Using MacOS Sonoma

This problem began a couple days ago. I have no problem accessing other sites on Firefox (and none for this site over years of use.) Can access site on Safari without problem.

Hello, My website www.bodymindwholeness.com will not loan on Mozilla browser for over 6 months now. My website loads just fine on all other browsers, just not Mozilla? I have tried to adjust every setting I can imagine with no luck. Why wont Mozilla allow my website to load and what can I do to fix the issue? Thank you Michael Hofrath

I have changed my default search engine, but the setting is not applied on my other devices. I have had to manually change it for each device. I have checked my Sync settings and everything is checked.

Hi there,

Earlier today I had to do a complete software reset on my MacBook Pro (running Sonoma 14.5). Prior to the reset, I had been running the newest version of Firefox and was signed in; I assumed that Sync was on and that it was storing my passwords and bookmarks.

After the system reset, I re-installed Firefox and signed in again, but none of my passwords or bookmarks are showing up. However, under connected services, I still see the old (pre-reset) name of my MacBook Pro, in addition to the MacBook Pro's current name.

Is it possible to retrieve my pre-reset passwords and bookmarks?

As of today, DirecTV is no longer supporting Firefox for watching live streaming. They show the attached image. Brave works, too, btw (Chromium-based browser). Do you know why this is happening? Has Mozilla been in talks with DirecTV about this? I use this feature every day.

Hello everyone, I have had a problem for a few weeks on the X platform. Some buttons no longer appear, notably the edit button on an image post or the "see" button for a hidden account (see images attached) Does anyone have a solution? I uninstalled ALL the extensions and restarted the app, but nothing works! Thanks in advance
