From the last two Firefox updates, I no longer can move sites screens around on my Mac Air laptop. Only one page at a time shows up and consumes the screen. I am no longer able to copy and past and move info to another screen. A couple of weeks agom I cleared my cache but not sure that had anything to do with it. Please suggest solutions. Is there an add on or something that needs adjusting?

Thank you.

For about the last month, if I click on a link in an email or on a website that should connect to another website, there's a long delay in reaching that second site. This did not happen before. The delays are intolerable and do not occur on Chrome, for example. I prefer to use Firefox, but I feel I have no choice but to use Chrome instead. Can my issue with Firefox be fixed? Thank you for considering this issue.

When I open Firefox it opens a maximized window with tabs, then it opens a minimized with a single tab, then it reopens a maximized window with all session tabs. Each window displays in succession, one window at a time.

I'm on desktop using Windows 11.

I just read a post saying this behavior was caused by the resist fingerprinting feature. Can someone explain how that causes the repeated opening of browser window 3 times. Is there a way to retain the anti-fingerprinting behavior w/o the multiple window opening behavior?

I have been using Thunderbird since about 2004 or 2005. It used to be somewhat instinctive to use in comparison to the current version. That's about 20 years ago. It now seems to have a minuscule amount of instinctual usability. My question / statement is where is the Tutorial. Like many products including Microsoft, make what they think are brilliant "improvements," and what they primarily do is cause confusion, frustration, greater difficulty in using the product and for many a wish they fervently pray for: "I I want my old thingamajg back."

I hadn't used Thunderbird since February of 2024 - LAST YEAR. Currently it is unrecognizable from then. I had been hospitalized with 3 stents, a pacemaker and heart valve, I'm back functioning and love life. However - It would have been simple to make a dozen short tutorials on enough things to easily do the basics. Pleading for donations and not making it simpler to use the product doesn't attract new users & make current users happier. I would be grateful if anyone can point me to some simple tutorial.

In my opinion what Thunderbird offers is too cryptic for me to process, I hope my post is noticed by a "Solver" Don't misunderstand me. I liked using Thunderbird for these many years because it was incredibly flexible, usable, and partially simple & instinctive. Today few people have the will or time to spend hours poring through help sheets that are a challenge and confusing to use.

Would appreciate your help.

When I open FF 137 on my iMac running OS 12.7.6, it just keep trying and trying with no link. When I try and quit it needs to be forced quick to stop running. There are no fire walls and it worked yesterday 4-5-25 just fine, but no go today. I tried replacing FF and still no luck, what do I try now, [email removed]@yahoo.com

I recently updated my Firefox browser from version 136. to version 137. and after the update I was unable to get online to any website I tried and Firefox would freeze and crash, generating a crash report that Mozilla probably didn't get because firefox couldn't send it. Safari was working, as was Chrome, so I know it wasn't a network issue. I cleared the cache and tried again and still nothing. I then uninstalled Firefox and reinstalled it from the Mozilla website, (had to use Safarii to get the Mozilla website) and still could not get to any websites. I'm on a Mac runnning OS 15.3.2 and I have a bootable backup of my machine that still had a copy of Firefox v 136 which i reinstalled on my mac and it works. What can I do to update to 137?

I have observed that firefox has a coloring problem. When firefox is minimized to the toolbar, after a while, maybe a few minutes, when it is opened, there is always black uncolored content at the bottom of the screen, occupying about 1/3 of the height.

Attached are two screenshots.

Is this a bug or config problem?

Occasionally, FF (Linux desktop) starts using a lot of memory. I kill tabs (sometimes it is OK to kill YouTube or X, sometimes not)

Eventually it starts impacting the system using so much memory. I terminate the FF instance. Often. More often than not. There is a separate task still running and I get the "Firefox is still running" when I try to restart. I then kill the remaining FF task via the OS or the process monitor. Then FF restarts.

Is this an issue with addons (I am running very few - uBlock Orign, and Privacy Badger and Cookie AutoDelete. Are the only ones active most of the time) Or is it an actual bug with garbage collection, and tasks getting away? Or is it an OS issue?

I restarted Firefox on my Mac earlier, which I think updated it from 136 to 137. After reopening it, web pages won’t load anymore. They either time out or just load indefinitely without doing anything. I went through the troubleshooting page and tried reinstalling it, which didn’t help. My computer’s firewall is off as well. I’ve tried refreshing it multiple times, and I get a message that Firefox has crashed before it actually refreshes. After that, pages will load normally for a very short amount of time (about 30 seconds) before stopping again. Pages are still loading normally on Chrome and Safari, so it’s only Firefox that’s having an issue. Does anyone have any solutions for what this could be/ways to fix it?

Hi, Being that OLED and AMOLED screens have become more frequent in recent years (and seem to be coming to stay) I am perplexed by the seeming impossibility of finding a way to make Firefox more friendly towards these devices.

I would like to use Firefox with a true black theme on its UI that would waste less battery and go easier on my screen's long-time durability. However, not only do I find that there is no option to do this in-built on the app, there isn't even support for external add-ons or thèmes that could get the job done!

There really shouldn't be any reason why, even if the Mozilla team are unwilling to code the option into the default settings, it couldn't be done through a user-made theme.

Instead, the solutions I've come across seem to span from third-party apps that require rooting the device to modifications made directly by decompiling the APK!

I know this was more of a complaint than a request, but heavy battery usage is a *valid* reason not to use something like a browser, which is likely to accrue several hours of use each charge cycle.

This *is* something Mozilla should care about.

TLDR;

Please point me to a way of making the Firefox UI AMOLED-black that does not require me to mess with the internals of an APK or void my phone's guarantee.

Sorry for the essay.

I am running Firefox in Windows 7 on a PC. When I start up Firefox, in WINDOWS Task Manager there appear between 20 and 30 instances of firefox.exe of different sizes in the Processes Window. I can End Process on most of them without shutting down Firefox or any of the other instances of firefox.exe. However if I shut down one listed with about 200,000K of Memory (Private Working Set), then Firefox shuts down and all other instances of Firefox disappear. If I open an new tab in Firefox, more instances of firefox.exe appear.

I have never seen this behavior before. I tried uninstalling and reinstalling Firefox, but the same behavior occurred. Is this normal behavior, or should I be concerned?

I have enclosed screen shots from the Task Manager. I also have a Dump File of a couple of the firefox.exe instances, including the large one, if that would be helpful.

Thank you.

If i search a topic, then search another topic, find a relevant page, then scroll back, it scrolls back to the original search topic and not what I last searched, then I have to type it again.

The image I uploaded is all I am getting. I even got on line one on one with my McAfee and they got on my computer. I need help guys. Is not just browse, I am also having issues accessing the website I know my account has been compromise. All I did different is add 2 adds on that were recommended by Mozilla and I removed them but it looks like the damage was already done.

Hello everyone,

I've been experiencing continuous crashes with the Firefox app on my iOS device, and it's becoming quite frustrating. Despite following all the recommended measures, the issue persists. Here's what I've tried so far:

Keeping only a few tabs open at a time. Deleting and reinstalling the app. Ensuring both iOS and Firefox are updated to the latest versions. Restarting my phone multiple times. None of these steps have resolved the problem. It almost feels like I'm being forced to either abandon iOS or switch to a different browser. Has anyone else faced similar issues or found a solution?

Thanks in advance for your help!
