Running Mozilla 151.1 (72455) on iPhone 13Pro Max using iOS 26.3.1 (a)

Anyone else experiencing the following?

If I am browsing any web page in private mode, then tap the "+" to add a new private window, I can not get to / tap on the navigation bar to type a URL. It ceases to be an input field. I have to exit the browser completely and start anew.

On a random basis, sites like msn.com, yahoo mail or outlook.com will freeze. Sometimes they may suddenly come back to life, but the normal fix is delete tab and restart tab. Long videos may also freeze. Have cleared history, and changed optimization setting but nothing helps. On 151.0.2 64 bit.

Hello! So long story short I've been looking to switch my default browser to Firefox and I would've done so by now if it wasn't for this small issue.

It's not anything super important, but it has been mildly annoying to deal with. I can't say for certain how long this has been an issue in general since I've only just started trying out the Firefox search widget about a week or two ago. The issue happens every time I use the search widget and seems to happen infrequently when I use my private tab shortcut too, but doesn't happen when I use the app directly however. After a initial search (when you first open the widget/tab), my keyboard would freeze on screen (sometimes fully opaque and other times a bit transparent in a similar way to a screen burn). I can only fix it by either exiting and re-entering the app/tab or by clicking on a link and having it redirect me. I have zero clue as to what could be causing this or if it is some kind of bug?

Any help would be appreciated, thank you!

I am using Firefox version 151.0.2 on android version 16, but I have been having this issue for months, since before 151.0.1. In some fillable fields on some sites, words duplicate as I type and/or the cursor jumps into the middle of a word. This is most frequently triggered by backspacing but can also happen when using numbers or symbols, such as when filling in a date with slashes or dashes. I've also witnessed it happen seemingly randomly.

Some situations in which this has occurred: -the tag field when creating or reblogging a post on the browser version of tumblr -the birth date field on my state's DMV website when trying to renew my car registration -multiple billing fields when trying to enter card information on a ticket vending site -this text box, the one I'm typing in right now to report this issue. Backspacing and using these dashes for this list both triggered the bug during the course of writing this up.

This has gone from merely irritating to actually being an obstacle (in the DMV example I could not get the field to accept any date format without duplicating and had to use the little popup calendar to select the day instead. What if that had not been a option?). My phone says both its software and Firefox are up to date. What else can I do?

As i have described beforehand, the app glitches when too much memory is occupied. I have to manually clear cache and force stop the app to contine using it. If sth can be done to optimize the app better, would very much appreciate it. Other than that, love the app and the services it provides. Please do fix it. Thank you

Using the home screen search widget with the composable toolbar enabled(which can't be disabled anymore) on LG G8 causes the keyboard to open as usual but will not dismiss with the button or completing a search where it will attempt to dismiss but fail halfway through animation and block part of the screen.

Reproduce-able with these steps on LG G8: 1 Close Firefox 2 Open search widget from home screen 3 search something in url bar 4 Press Enter 5 Go to homepage, screen off, take a screenshot, or click on another text input box to make keyboard go down, sometimes with glitchy animation.

Not sure the exact cause but it also happens when browsing normally, i think its when a website loads and opens keyboard on its own.

Doesn't seem to happen on Samsung A16

switching windows in and out Firefox android seem to reload the open page, this sometimes means significant waiting time and in case of scrolling pages the loss of your last position

just agreed to the new update for firefox and now my scroll bars will not work properly. they keep jumping to the far right hand side of page and when moving the scroll bar to the left so I can view the whole thing it will not stay. it jumps back to the right side.

Hello,

I’m experiencing a serious issue after updating Firefox to version 150. Since the update, Firefox frequently freezes and crashes, making it almost impossible to work normally.

My laptop has 16 GB of RAM, and I’m using Windows 10. When I check Task Manager, I can see that Firefox’s memory usage suddenly increases to around 7–8 GB, then drops back down to around 3–4 GB. The memory usage keeps fluctuating heavily.

Also, the number of Firefox processes/tabs in Task Manager keeps increasing, and eventually the browser becomes completely unresponsive.

Could you please investigate this issue and let me know how it can be fixed?

Thank you.

Hi there,

I am on a MacBook Air M3/8GB ram. I was really wanting to use Firefox due to your stance on privacy, etc. but here is my experience:

Yes, I keep a lot of tabs open - I do try to group them and hope that tabs in closed groups are deactivated, but I don't know this at all.

If I use Firefox all will seem well until my machine sleeps. On waking, it is excruciatingly slow - we are talking multiple seconds to even switch tabs or get the cursor to be "hot" when filling a form. Upon trying to quit (restarting being the usual first step), FF will ask confirmation and then close the windows, but will not completely quit, requiring me to force-quit. On restart it seems to behave again, at least for a while.

While I do see some evidence that others have this issue (memory leak?) there are no real methods or answers as to how, if at all, to fix this. It took a lot to get everything on FF working the way I like after leaving Chrome, but I really can't deal with this, and I think I will be looking at switching again - I guess to Safari.

I would love to know how to fix this, but really I don't imagine this is due to my system as much as the FF browser. That said, if you ahve any ideas, I would be open.

Windows 10 Open Firefox (151.0.2) Google "does alton towers still run in the rain"

My CPU then goes to 100% continuously. Why, CPU occupancy has only gone up in the last few weeks. This happens in a lot of searches.

Firefox is being flagged on my Android tablet as having too high background battery usage and it wants to put FF in deep sleep. This has just started happening. Also in the last several months, FF keeps freezing on my Android Tablet and I constantly (daily) have to clear the cache in the app. What has changed? If this continues I will have to uninstall this product.

当把Firefox置于后台一段时间，甚至是很少的一段时间后，就需要重新加载页面，这个加载过程很慢，通常需要几秒至几十秒，大多数时候都在十几秒。 这对于一个移动端浏览器来说是严重性能影响，因为很多时候可能只是随手搜索一些东西，打开或加载过慢尤其影响使用感受。 像其他浏览器，比如我正在使用的其他浏览器Edge或X浏览器，基本上可以无论何时点开直接使用。

Firefox MAC freezes intermittently , will get spinning beach ball and status shows Firefox (Not Responding) and must force quit FF.

Sometimes FF after fresh down load from the official FF site for MAC will work great for an hour or half a day and then out of now where go into the spinning beach ball , and unable to enter data into any field - completly bricked and FF status shown as Not Responding. Tnis could happen immediately, or after an hour or anytime within a day or two.

No way of deciphering or determining what in the heck triggers it or why - way way too many factors and settings and variables both within the FF registry and the macOS and the activity I may or may not be doing at any given time.

I will say I experienced this when all apps on my MAC were shutdown, no apps up and running, but I do use Backblaze, Mai Backup X, Malwarebytes, Dropbox, MS NTFS Tuxera, DriveDX which all have ongoing background tasks running all the time or at least in the background from time to time.

However, I have used this setup for the last few years with Firefox MAC with absolutely no hiccup whatsoever.

And then immediately after the last FirForx update on Tahoe, just before I applied the latest 16.5.1 Tahoe upgrade is the intermittant freezing with FF started.

Could this be a FF / Tahoe incompatibility issue?

If not, does anyone out there have anything to fix this?

And yes i did a complete uninstall of all of FF hidden Library folders as well as the "firefox.app" itself - if anyone tells me to uninstall all the hidden FF folders and files in ~/Library one more time, then forget it, I am done using FireFox. Been there and done there a number of times the last week, exhausted with that, and doesn't do a thing.

And yes kept deleting and creating new FF profiles and did not fix the issue.

So does some great genius Mozzilla FF Mac SW engineer have any clue as to the real issue and the real fix without sending me on a wild goose chase?

thank you. clb6
