Firefox Support Forum

A few days ago links in messages stopped working in Outlook (Microsoft 365) on my Windows 10 Pro 64-bit PC.

Good ol' Microsoft support reset Firefox on the PC and I lost all bookmarks, history and personalized settings. Tried to copy data from Old Firefox Data file into profile on reset Firefox. Didn't work. Uninstalled and reinstalled Firefox and tried to copy data from old profile to new profile. Nada.

Only option now is to try to sync Firefox on my Mac to new install on PC. I'll still lose some bookmarks and history but it will be better than what I have now. I have a Firefox account on both devices but when I log in to Firefox on the Mac I cannot find anything pertaining to sync.

Problem one: how do I navigate to sync in Firefox for Mac. Problem two: when I bought the Mac 6 years ago I tried to sync Firefox on my PC to the new Mac. For some reason Firefox synced the empty new profile on the Mac to the old PC. I lost all bookmarks and history accumulated on the old PC! I do not want to go through that again.

I have never found anything on Mozilla that clearly explains how to control which way the sync works. Must be certain that I'm copying all the bookmarks, history, tabs etc, from the old device to the new on and not vice versa.

Dear Sir/Madam:

I am using Firefox Browser 102.15.1esr (64-bit) on a MacBook Pro Ventura 13.5.2.

I have been using the www.dictionary.com website for a long time, but recently when I attempt to go there, I keep getting the error message as follows:

Unexpected Application Error! FM.findLast is not a function

I tried clearing caches under Privacy & Security, but the problem persists.

(Meanwhile, I can visit www.dictionary.com on Safari and Google Chrome.)

Could you please let me know what is going on?

Thank you,

Roland

Firefox automatically updated on 18/09/2023. I now get the 'unable to connect' message for many bookmarked tabs (e.g. hotmail sign in). I have not changed any firefox settings and I can connect to the sites in Chrome. I'm running mac 10.15.7 Is this a bug or do I need to change a setting? Thanks in advance for help... Tim

I am told to disable pop-up blockers in order to have a payment verified. I do not know what pop-up blockers are, I do not know where they are. When I go to Settings and search for pop-up blockers, I am told "Sorry! There are no results in Settings for "pop-up blockers"; and instructed to visit Firefox Support. I have been sent on this circular quest three times now. Please help me.

Hello Firefox Community,

I've been a long-time fan of Firefox's bookmarks management system, but over the past year, I've encountered a persistent issue that's affecting my productivity. I regularly use the bookmark bar and organize my bookmarks into folders. However, any changes I make don't seem to stick and get reset after a period of time. This is especially frustrating as I heavily rely on bookmarks to keep my browsing organized. Problem Details

Here's what typically happens:

1. I add a bookmark to a specific folder or position, either in the general list of bookmarks or on the bookmark toolbar.
2. Sometime later, that bookmark leaves its designated position and moves to the bottom of the unsorted list of bookmarks.

Devices and Operating Systems

• MacBook M1 2020 running macOS Monterey
• Dell Alienware 17 r5 running Windows 10

Both devices have the latest version of Firefox installed, and I use Firefox Sync to keep my bookmarks and settings consistent across these devices. Suspicion

I suspect that this issue occurs when I make a change to bookmarks on one computer and then open Firefox on the other computer. The bookmarks seem to reset, possibly due to some issue with Firefox Sync.

Looking forward to hearing your thoughts and possible solutions!

Kind regards,

I got these errors on my console when I load the page. Everything is correct, but after doing some actions (button clicks or text inputting), the web is crashing, and I get these errors in the console, and it starts infinitely reloading.

Currently on macOS Firefox 117.0.1 and in the last week I noticed I can't authenticate with my Yubikey anymore. The browser will prompt for the key ("touch your security key", etc.). While the prompt will go away after I activate my key, the browser window won't advance past the authentication page. Short story-- I haven't been able to use my Yubikey for any site recently.

So over this. Have been using FF for decades. Why FF does now randomly forget my previous session. Works fine for momths and then suddenly all previous session tabs are gone and recently closed windows loads a blank tab.

And yes, we have tried all the supposed fixes.

I have noticed that when watching video using Firefox (Youtube, Youtube TV, Netflix, Nebula) that randomly, the video will just cut to black and then fade in. Sometimes quickly, sometimes slowly. A hack I found that fixes it is just entering/exiting fullscreen, which seems to "reset" the video player. I do not know what causes this, it just shows up when I am watching things. I have noticed that it seems to show up when a video cuts from a darker scene to a brighter scene, although this is not consistent. I am confident that Firefox is the issue because I have watched videos extensively in Chrome, where it does not show up. This also persists if I connect an external display and mirror or extend my screen to it.

I am using a 2023 Apple MacBook Pro 14", with the M2 Pro SoC. My OS is macOS Ventura 13.5.1 .

I have tried solutions that involve messing with the gfx.color-management settings in the about:config page. I also have hardware acceleration turned off, if that is possibly the cause.

Does anyone have any clue as to what causes this?

I am unable to log into facebook after inputting my password and 2FA. disabling all addons does not help. It is stuck on the "This was me" screen in an infinite loop.

I have used Firefox on a 27" MAC for many many years. In fact I have used Firefox on many macs since Firefox was first offered. As of the last update or browser upgrade offered by Mozilla for Firefox for Apple desktops, most all streaming video service no longer work. YouTube, Amazon Prime, and Netflix all stall after a minute or less of selecting a video from the above vendors. I get the little spinning arrow, and then a screen message that states that my ISP is not providing me with enough bandwidth to stream video. Absolute nonsense. Using Safari I have absolutely no issues, problems, stalls, buffering, error messages etc., and the experience is what I used to get from Firefox. I have lots of bandwidth available, and have had a professional network engineering service provider check my internet connection. Even if I make sure no other tabs, applications or other iterations are running, ONLY Firefox, it stalls and will not play video. Then I get another screen message that states that "maybe if you restart your device you may be able to play video". While I realize that Firefox is free, I still think I should have a reasonable expectation that it will continue to provide buffer, stall, and hang free performance when I want to watch YouTube, Amazon Prime and or Netflix.

I have been using (VIEWING articles in // saving articles TO my) FIREFOX "POCKET" for more than a year.

I have the pocket ICON on my upper toolbar. But ALL that seems to do is allow me to ADD an open page TO Pocket. I have NO clue how to simply **Go t o POCKET** and VIEW any / all my saved items there.

Good God, WHAT is the secret handshake??! ...in trying to figure this out I see numerous things telling me to SIGN IN to pocket ... IF way back when I began using pocket I MADE a USER NAME / Password for it, that info is long forgotten. I HAVE a FIREFOX account ... was sent therewhile supposedly (according to Firefox" HELP") to 'sign in' to my POCKET account. Only took me to an overall FIREFOX account page - wherein NO LONK there referred AT ALL to POCKET.

I 'SAVE' to my pocket (ICON) almost daily. NEVER need any kind of sign in for this. NOW I want to LOOK AT / READ some of these - BUT FIND NOWAY TO GET THERE. ICON omly SAVES a page.

Ridiculous. HOW do I VIEW / SEE / FIND /READ my saved pocket items?
