Trying to use a virtual terminal for my credit card processing for my business but firefox is not giving access to share location to the site even after I have manually allowed location sharing. This is the message I receive when I try to use the terminal: Sorry, we can’t load Virtual Terminal. We couldn't access your location. To use Virtual Terminal, allow Clover dashboard to know your location on your browser, then refresh the page How do I get this corrected?

I've seen the archived suggestions do disable quick find. They were to uncheck 'search for text while typing'. I went to do that and it was already unchecked. How can I disable this? It's a problem when doing math homework.

Cloudflare provides a web site https://www.cloudflare.com/ssl/encrypted-sni/# which can test Encrytped SNI. My browser is configured in about:config for ECH as follows

network.dns.use_https_rr_as_altsvc true network.dns.echconfig.enabled

When I run cloud flares test I get a failure for ESNI, should this occur?

When I go to the ABC News website an icon in the URL slot tells me I have granted this website additional permissions. I don't grant additional permissions. I don't even accept cookies. I clean my computer after EVERY browsing session with CCleaner. I am thoroughly disgusted with the incessant onslaught of cyber intrusion on my personal privacy. I don't know what additional permissions I supposedly granted because I would never consciously grant anyone any permission. My question is how do I remove these additional permissions that I miraculously granted? Now I have blocked automatic play of audio/video on the website. I see that as a removal of a permission not a granting. Is this why I am seeing a granted additional permissions icon? Or am I just going to have to stop using ABC's website? Any guidance you can offer is appreciated.

Dear Mozilla Team,

I use Firefox as my default browser. MS Teams gives a failure message: "Your browser doesn't support audio". I have to use a phone for audio communication. How to correct this failure?

I am 66 and can't read the tiny fonts on my saved bookmarks... how can I make them bigger. I know how to make web pages bigger but HOW DO I MAKE THE BOOKMARK FONTS BETTER this is ridiculous how small they are and no way to change them... . WTF over !

marionette.enabled is set to "False" but the browser still has the obnoxious orange address bar with the robot head providing the message Browser is under remote control. I did nothing to turn on this feature, and I want it off. Help!

Hi to All I am user of firefox on several windows 10 computers, probably 7 different computers. I want to point out the huge memory usage in firefox on absolutely different computers and I want to resolve this brainless problem. At beginning, probably in 2016 I began to notice big memory usage in firefox with many of tabs opened, probably over 100... yes, 100 tabs is too much but even so, memory usage seemed inappropriate to me, especially when before it working on computers with low memory installed. I started solving huge memory usage by restarting firefox, usually killing firefox through taskmanager on windows. But about a year ago I started using Firefox on several computers for loading some pages and I programmed automations of some tasks on this pages. This tasks includes clicking on buttons on pages, entering values and loading new links, subpages.... This all always in one tab and in one firefox window and after some time, firefox on every computers start using over 3GB of memory, in one tab and one window??? It is galactic amount. Of course, processes on computers was crashing. Depending on the page, that was severed from 12 hours to several days. Therefore I started some researching in this and I tried to reduce memory usage by settings in about:config: browser.sessionstore.max_serialize_back = 0 browser.sessionstore.max_serialize_forward = 0 browser.sessionstore.max_tabs_undo = 0 browser.sessionstore.max_windows_undo = 0

browser.sessionhistory.max_total_viewers = 1 browser.sessionhistory.max_entries = 1 but this last parameter have no effect, why??? After this settings my solution working, but it is little bit breaknecking: After some steps in automation I open new tab and close prewious tab and load page again and memory usage drops from 1,5GB to approx 500MB (Due to browser.sessionstore.max_tabs_undo = 0) Excuse me but this behaviour is very terrible.

browser.sessionhistory.max_entries I trying to reduce to 1 but this setting have no effect (I can back to new tab page), sometimes take effect only in just running instance when I change it and number must be higher than 5 or 10? Sometimes take effect, sometimes no, but after restart firefox again without effect. Due to this nonsense memory accumulation per each one tab I want to tweak firefox on my working computer. I not need galactic number - 50!!! or even more? pages in "back button" in memory per each tab, and there are no way to reduce it without restart, only way to release memory is set browser.sessionstore.max_tabs_undo to 0, open new tab, and close old tab and then memory usage very drop...

Next, I searched in about:config by keyword "session" and found browser.sessionstore.cleanup.forget_closed_after default equals to 1209600000 which means 14 days... oh so galactic... Normally firefox is unusable after few days without restarting, developers recommends to restart firefox for memory free up, but default value for this option sets to this huge number? Are they kidding users or what? After all, with this setting and behaviour, it almost never applies. And how much such nonsenses does firefox still contain? I am very angry for this several-years lasting memory issue because firefox is my favourite web browser. According to what I found on the internet, developers stubbornly ignoring or refuse to find effective solution but it would be so simple. Probably only memory release button would suffice, which would remove all cached pages. But "true release/free up memory button". User would had to accept, that all back/reopen actions will be discarded. No dummy/parody button in about:memory. ooooh "minimize memory usage" which free up probably max of 15%, normally about 5% of used memory. I tried "firemin" too, but this is next parody... this rapidly decrease of memory which appears as super, but causes totally pause of processes on page and when you need do some action on page, another time is needed for reloading(wake up) the almost same amount of memory as before minimization by this program - in short, this is suitable just only for temporary minimization of memory usage, something like pause firefox.

Therefore please, Can someone really help? (Not kidding like: about:memory, firemin or other unusable "nosolutions") This problem has been consuming me for so long that I quietly started to think that the only way to resolve it is to reprogram and recompile my own firefox, but that is quite unrealistic for me.

Recently when my computer shuts down (my battery is dying so it happens often) and the previous session are restored, they are not from my previous session per se, they are from an older session. What can I do for this to stop happening?

Thanks in advance

I mistakenly deleted my firefox browser, I am running Mac OS 10.7.5 with a SSD on a Mac Pro desktop. I have been unable to download a new firefox browser because of the OS and hardware limitations. I sorely miss firefox. Is there any way to get an older version of firefox which will run on my computer? adnicastri@aol.com

As a security feature on a shared computer, I'm wondering how to restrict the ability to alter add-ons and I was hoping that there was a way to disable Safe Mode (aka Restart With Add-ons Disabled')

I have been using Firefox (my primary browser) with Express VPN for two years. Lately Firefox will not download a home page if the VPN is connected. If I disconnect the VPN, Firefox will load, but at a very slow rate (close to a minute). I have tried starting Firefox with extensions disabled which had no effect. I have also communicated with Express VPN and have submitted diagnostic data to them. They state that since Chrome and Edge works fine with Express VPN, that the issue is with Firefox. I have used Firefox for quite a while and like the platform . . . but I must use a VPN and if the choice has to be made, I will become an Edge or Chrome user. Any suggestions will be appreciated.

Hi!

Since most content is in English and search engines always link to the English version, I usually browse the english version of mozilla pages. But here on support in particular I have to contend with the pathetic date format where you can't tell which is day or month or year. So why can't I find a way to set the date format. Even the majority of tiny websites/forums have an option to specify the date format.

Lately almost every time I use Firefox, RAM usage goes up to 5 GB, CPU usage goes to 100%, and my PC becomes unusable until I kill Firefox processes and wait 5 - 10 minutes for virtual RAM to be cleared out of disk and disk usage to return to normal. This is much worse since the last update, basically making Firefox unusable. Is anyone working on fixes so Firefox doesn't need 5 GB of RAM to open one simple web article?
