I am using the latest version of Firefox with Mojave on a Mac.

Lately I have experienced slowness despite the fact that I didn't add any software and I have Norton checking for viruses. Recently I got a message "Your system has run out of application memory" when I had 5 tabs open in Firefox. I checked Activity Monitor and it showed Firefox using 1.16 GB. 7 other apps were open, the next one with the highest memory usage was Mail (465 MB). Activity Monitor showed 30 instances of FirefoxCP Isolated Web Content entries.

I attached a screen capture showing what Firefox was using in one of these instances. Is this "normal" with 5 tabs open?

I closed the open tabs and quit Firefox. Memory usage by Firefox went down, but after a short time the problem happened again.

A search on the internet showed lots of similar complaints about FirefoxCP Isolated Web Content. Is this a known bug? Any way to avoid this problem?

Thanks.

why do you stalk and bother the users? i do not want to update! without warning you alter things i do not want you to alter. you take things out so people have to use risky 3rd party addons.

Hi,

When using the right click menu on a PDF item in the Download Library (Ctrl+J) option Open In XYZ PDF viewer opens the pdf in chrome!!! option [selecting] Always Open In XYZ PDF viewer opens the file in chrome!!! option [deselecting] Always Open In XYZ PDF viewer opens the file in FF!!!

Double clicking on a PDF item in the Download Library (Ctrl+J) also opens the file in chrome!!!

This is totally wrong, please fix it asap. Thx

I had two Firefox windows open. One had 100+ tabs open, the other had around 5 open. Like a klutz I accidentally closed the window with the 100+ tabs open instead of the other window. Now when Firefox restarts it opens the version with the 5 tabs.  :-( I read about lost tabs in Firefox. I have found a file with the 100+ tabs in it. It is called: upgrade.jsonlz4-20221007134813. But what do I do next to restore Firefox to restart with the 100+ tabs version? Thanks.

Greetings!

I would like to be able to open selected links via the search tool with CTRL + Enter, like it is possible on most browsers. Basically, I do CTRL + F, select a text which brings me to a link I was looking for, and do instantly CTRL + Enter to open this link. Currently, this shortcut only toggles the ability to see all matched texts and doesn't open the link.

Do you know if it's possible? Thank you!

What is with Firefox lately. Endless problems with screen sizing, light dark mode. But what is really pi**ing me off is the inability to connect to certain web pages. No I don't have a any spyware or viruses (I have scanned with 3 different programs) and I have no problems with connecting to the pages with Chrome or Edge. I'm getting the error messages

Did Not Connect: Potential Security Issue Firefox detected a potential security threat and did not continue to www.amazon.ca because this website requires a secure connection.

Did Not Connect: Potential Security Issue Firefox detected a potential security threat and did not continue to www.ebay.ca. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details. Firefox detected a potential security threat and did not continue to www.google.com because this website requires a secure connection.

Did Not Connect: Potential Security Issue Firefox detected a potential security threat and did not continue to www.google.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.Error code: SEC_ERROR_UNKNOWN_ISSUER

And I get the same warning with Amazon, eBay, my email client Shaw Mail, Google Search, and several other pages that require a login. Is there anything I can do to fix this as I'm really starting to rethink my preferred web page browser?

I'm confused about sync when it comes to sessions. Sessions is not one of the options.

A few days ago, I open Firefox and my profile was broken. Nothing worked in the way of toolbar addon buttons, contest menus, etc. I narrowed the problem down to the session store files.

The session was still present. I could scroll thru it, and select tabs, but hat was about it. Fortunately I was able to get things back working again in a fresh profile, but it was a tricky exercise.

My desktop sessions sync with my phone. Is the re a way to perhaps sync sessions, and do it recursively so you don't get a mess with duplicates and discarded tabs?

I used to to use Tab Session Manager until a couple years ago when it began destroying sessions, and there was no way to retrieve them. Even the supposedly repaired version couldn't reverse the process. Had something to do with the sessionstore-backups folder, so I don't know if I can trust it now.

Hello,

In a previous version of firefox, I could right click within a text area for example, which would allow me to check my spelling. Since upgrading (which was actually from a higher Beta version, to the latest current stable - a new profile was created), I had not had this option. As you can appreciate, it's a very handy tool to have, so I have been attempting to get this function back today.

Within my language section, initially there was only 'English [GB]', which was as it should be. I had 'check spelling as I type' checked also. This did not automatically check as I typed. It did not check at all, not could i right-click to check spelling.

I have since added 'English [US]' to see if this would then allow me to remove and reinstate 'English [GB]', but it did not. I then added a third option which was 'English [CA]'. The config allows me to remove only 'English [CA]', which when pressed removes it from the list, but by pressing the 'set alternatives' button again, you can see that it has returned.

I have since managed to get firefox to check spelling in English [GB] by adding 'British English Dictionary (GB)' (https://addons.mozilla.org/en-GB/firefox/addon/british-english-dictionary-gb/), but now I am also stuck with English US and English CA. EN-US does not allow it to be removed whatsoever, even though it was only there after I manually added it and EN-CA allows me to remove, but returns. No option to apply and restart firefox appears (I've seen this appear in another user youtube video on the subject). Closing and opening makes no difference.

How can I removed English US and English CA please?

6 images attached, in sequence order. Between images 3 and 5 you can see CA being removed and returning (and also no option to remove US). The last image is what I am now trying to get rid of.

i want to be asked about every download where it going to be saved and even though i changed the settings long time a go the downloads go straight to the default folder

help!!!

Linux Since the last 'automatic' update, Firefox hangs when started, but doesn't show any GUI.

Many experiments later, I can report the following progress:

- I started firefox from the command-line, hoping to see some output (no luck there), and eliminating problems with the window manager launcher (XFCE) - Firefox launches, but in triplicate: 3 instances are running (of firefox, _not_ firefox-bin) - There is no console output. - Running inside gdb shows threads entering and exiting, no errors. On ^C, there's just a message about exiting the current thread. - If I kill two of the instances, the GUI appears, so it seems they are blocking each other - I wanted to trace the startup sequence, so I did `strace ./firefox 2> log` and behold, firefox started! This is why I am reporting this on the actual started firefox. - Which makes me suspect a 'race condition' - surely the strace is slowing things down, allowing one instance to create the GUI. Some code which is not lock-protected?

I'm afraid this could happen again in next session, which is why I report this first, before trying to restart FF.

i have a login to Harris county /toll Road Authority. A few weeks ago, it quit loading. When I click the bookmark, the tab shows motion, but after that, only a blank screen. I have tried the same web site on MS Edge, and it loads without a problem. Tried settings change to no proxy, adding the login to exceptions - no change, it still loads a blank screen. What is going on?

Windows 10 Lenovo Yoga laptop, no GPS chip from its spec sheet. Firefox browser running bing and google maps thinks I am "near" a place I was two weeks ago. I was never actually there, I was 20 miles away from where it thinks I was a couple weeks ago and now I am 320 miles from there. Firefox is up to date 105.06 from the about field says current.

Chrome websites know exactly where I am, and has been correct all the time. Bing Maps, Google Maps and MapQuest Map know exactly where I am on Chrome!

Why do they think I am hundreds of miles away when those same map websites are run on Firefox?

We travel in an RV so every 4 or 5 days, we move 50-100 miles. Microsoft Map thinks I am in the same spot as Firefox, and I have changed its default location each time we move. But it thinks we are still someplace else, same as Firefox.

I have done all the usual checks, troubleshooting mode, reboots, location settings, checked to verify NO Proxy is set. No VPN is running.

I really want to keep using Firefox, but this is begining to make me wonder why as its been going on for a couple months now. We have been traveling in an RV for 6 years during the summers, and never noticed this before.

I did buy an external GPS dongle for Windows but none of the maps programs see it, except the app made to test the dongle. BU-353W10, a windows 10 gps dongle. I tried a couple others, similar results, they cannot see it.

disable pop=up sign-in with google prompt LAPTOP WINDOWS 11 FIREFOX 105.0.3 64-BIT 1. Over the last few days I have been getting a sign in with Google prompt on most websites I visit. Please refer to the photos. This looks identical to the Google generated promt, however in my Google account settings I have this option turned off. Is this a Google bug or a Firefox thing? With all the other annoying popups these days, this is just another irritation frustration to view a website.

I USE DEV TOOLS from FIREFOX TOOLS TO FIGURE OUT IF IT'S FIREFOX OR GOOGLE CAUSING ISSUE. HERE IS ONE OF 50 LINES RELATING TO GOOGLE/TWITTER/FIREFOX CONVERGENCE

(ALSO, I USE UBLOCK & LASTPASS)

LINE FROM DEVELOPER CONSOLE WHEN I OPEN TAB TO TWITTER LOG-ON PAGE:

20:36:03.881 Google Analytics and Tag Manager is being shimmed by Firefox. See https://bugzilla.mozilla.org/show_bug.cgi?id=1713687 for details. sandbox eval code:1:9

I DON'T WANT TO CLOSE THIS POP-UP BUTTON EVERYTIME I GO TO LOG IN AT TWITTER, IT'S NEW. I HATE IT. HAVE DELETED TONS OF UNKNOWN FILES IN MY USER FOLDERS TODAY, NOTHING HELPED (LOCAL/GOOG FOLDER & TEMP FOLDERS). MAYBE I NEED TO RESET SOMETHING IN CONFIG OR A REGEDIT SETTING FOR FIREFOX. I'LL DO ANYTHING. Thanks!

I have two computers with same version of windows and Firefox. One shows Vulnerable passwords alerts not showing, the other doesn't. Show alerts about passwords for breached websites is selected on both

When my Norton VPN is turned on, I get the following error message when I try to access Staples.com. This does not happen in Edge or Chrome.

You don't have permission to access "http://www.staples.com/" on this server.

Reference #18.44697c68.1665668757.1bd3f14e

Entering onedrive , I can see all folders, except recycle bin.

Entering recycle bin, I get error 103.

Doing same steps to enter onedrive thru Edge, I get no error.

There must be an incompatibility of onedrive thru firefox.

I also cleaned registry with CCleaner, without any success.

Please inform me of how to proceed.

Hi, Is there any way I can view contents of a previously closed webpage? I got an estimate for a health procedure, but did not take a screenshot. Now when I go back via link (provided to me in email) to view the estimate, it's no longer there. Thank you!
