Signed into Wall Street Journal. Clicked on a subject. Got this on a screen Application error: a client-side exception has occurred (see the browser console for more information). Tried to ask the question at WSJ, Their trees are hard to get through. What is a browser console?

I've had an issue on my Mac Mini since (I think) I bought it ~1.5 years ago. Firefox essentially stops responding randomly. When it happens, I can usually still scroll through the page, but I'm unable to click on any links on it. Other things like hovering over things that might change color also stops working. When it happens, it happens to all tabs that are open. It usually eventually comes back on it's own after a couple minutes. The weird thing is as soon as I load any other external application, even something as simple as Settings or Preview, Firefox will immediately spring back to life. Only a couple common addons (Ublock Origin) but it happens even with all add-ons disabled. It's sporadic, sometimes I can go all day without it happening, other times it happens every few minutes.

It's persisted through 3 different OS upgrades and countless Firefox versions. I've tried everything I can find about troubleshooting Firefox on mac and nothing works. It's not a resource thing as it happens with only Gmail open sometimes and Firefox being the only thing running. I'm at a loss and looking for anything that might help. I've never seen this issue on other Macs I've used Firefox with.

Recently, I lost the ability to sign into my bank account using Firefox on my iMac. Thankfully, I kept Safari on my iMac. It works fine. What can I do to use Firefox to check my bank account again?

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have macOS

I had my Dell laptop crash. I reinstalled Windows 11 Pro 10.0.22000 BUILD 22000. I installed Firefox 131.0 (64-bit). Before the crash I had a Microsoft version of Firefox. Now, I CANNOT get Firefox to save my names and passwords for the sites I access. It's frustrating. What else can or should I do to get this to perform as advertised??? Thanks for any help.

Downloading emails became grindingly slow and so I re-installed Firefox only to find that years of saved emails across many many folders, as well as contact addresses have vanished.

Help please

I have tried every solution I can find on the web. The McAfee Webadvisor is nowhere to be found in programs, in settings, even when I look at services. I've tried the block popup solution but I'm still getting them. Anyone have any other ideas? These things are driving me nuts and away from using Firefox because i can't get rid of them and they only show up when I use Firefox. Thanks in advance for any suggestions.

I realize that the various stories that are presented are simply and excuse to provide more space for advertising but they are so very overloaded with superfluous, repetitious, word and story extending information that I am really sick of it. The stories are usually good but SO over stuffed that anymore I just go straight to the end of the story and skip all the stuff in the middle. I would not be surprised if many others are doing the same thing and thereby also avoiding the a lot of the many advertisements that are also stuffed into the story. So the story extending process seems to be defeating your purpose. I suggest that stories that are a little more to the point might be read more (and more ads read more) by people who don't have all day to wade through those terribly verbose stories. Roger DeWeese

Unable to use Firefox to access Youtube. Problem started either late last night or early this morning. Whether using a bookmark or entering "Youtube.com" manually, the browser window merely acts as if I'm not even connected to the internet before finally just giving up.

Have tried using both 115.17.0esr (64-bit) and 132.0.2 (aarch64) versions of Firefox (each using a different computer), but YouTube refuses to load.

By contrast, YouTube has absolutely no problem loading using other browsers, the site loads almost instantly.

I have tried the suggestion to change private browser mode but this doesn't not help at all. Nothing is restored to normal functionality for non private browsing. I also reinstalled Firefox with no resolution. What else can I do?

I've added https://x.com as an exception site but it is still blocked.

https://x.com/mozilla doesn't work either

Error message on the page:

"Something went wrong, but don’t fret — let’s give it another shot.

⚠️ Firefox’s Enhanced Tracking Protection (Strict Mode) is known to cause issues on x.com"

After 2 days it used to finally load without my doing anything, but not now. I never loads using Firefox.

https://x.com is added as an exception, but obviously ignored.

Tried You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.

NOPE

Tried: Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Settings), click the padlock icon (Clear cookies and site data) for the domain in the selected tab.

"Remove the Cookies" for websites that cause problems:

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

   switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
   do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

NOPE - lost all my bookmarks, extensions, settings - not going there again thank you

as for:

You can check for issues with Enhanced Tracking Protection. Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.

   click the shield icon for more detail and possibly disable the protection 

the sheild has a slash thru it saying "enhanced tracking is off for this site" when i put my mouse over it.

Hi,

I am in the pharmaceutical industry and using ectd program, which is producing an xml backbone (directories) containing pharmaceutical information (pdfs). Only internet explorer can show this. Chrome has recently lost this ability. Firefox shows only some headings, like reading the index.xml only and not detecting the other directories. Is there an option/addon so I can view the contents correctly? I cannot attach the export of the ectd program (index.html & backbone/directories) so you can see to what I refer to, only the pics.

Thanks! Ryk

Hello Firefox is my default browser Now I have undesirable ads in the Promotions tab. Of course they disappear if I delete the Promotions tab, but the Promotions tab is very convenient. I can't mark them as spam. I don't have this problem at all with Chrome. Please tell me what to do. Sincerely

I am a long time user of Firefox (I remember the Netscape days...) Recently, I have come across rumblings about Firefox privacy defaults. At first i dismissed it as the usual whinging, but then i started to see what appears to almost be forks of Firefox. I have already ditched Thunderbird because of their nonsensical thread defaults. Surely, Firefox with its privacy focus wouldn't be making privacy decisions from collaboration with other browser companies like google & Microsoft? One of the early really great privacy innovations was in containers, but it is still an extension. Why? Because of the architecture of Chrome, its is not possible to have containers in chrome engined browsers. So is that why Mozilla didn't progress containers? Did the money from Google for default search engine (shame on you Mozilla) come with strings attached? I came across Librewolf which mostly use the Firefox code but with much more stringent privacy defaults, and with bundled ad blocker as part of the default installation. How can it claim to be more privacy focused than Firefox when it uses Firefox code? Firefox is supposedly the privacy focus browser so why is it following what Chrome and Edge do? They will NEVER gain lost market share by watering down their privacy settings which is the reason to even exist. It just antagonizes users like me. Or is that the point, a nice easy progression till oblivion and we all then accept an advertisement riddled internet.

all my tabs from open session disappeared?!?!?

and no way to restore it; the option disappeared and I never erased it or close any of the tabs manually and it was on sync. Where did they all go ? I can see now the history from my laptop mixed with my mobile under the history tab but the session disappeared?!?!

Firefox use to be EXCEPTIONAL and 2 years ago it star5ed to go downward; please convince me to stay loyal and not switch to brave or opera; this is becoming worst every months.

I did everything I found with ChatGpt and nothing works:(## Recovering Lost Tabs in Firefox Android

I understand that all your open tabs in Firefox Android have disappeared, even though they are synced. Don't worry, there are ways to restore them and reopen that session on your mobile device.

• • Here are the steps to recover your lost tabs:**

• • 1. Check Recently Closed Tabs:**

• Open Firefox on your Android device.
• Tap the three dots menu in the top right corner.
• Select "History" from the menu.
• Choose "Recently Closed Tabs" from the History list.
• This will display a list of recently closed tabs. If you see the session you're looking for, tap on it to restore all the tabs.

• • 2. Use the "Restore Previous Session" Feature:**

• If the "Recently Closed Tabs" option doesn't work, try the "Restore Previous Session" feature.
• Open Firefox on your Android device.
• Tap and hold the "Home" button.
• A pop-up menu will appear. Select "Restore Previous Session".
• This will restore the last browsing session you had open, including all the tabs.

• • 3. Check Your Synced Devices:**

• If the above methods don't work, check if your lost tabs are open on another synced device.
• Open Firefox on your computer or another mobile device where you are logged in with the same Firefox account.
• Look for the lost tabs in the "History" or "Recently Closed Tabs" section.
• If you find them, you can open them on your Android device by syncing your browsing history.

• • 4. Contact Firefox Support:**

• If none of the above methods work, you can contact Firefox support for further assistance.
• You can reach them through their website: https://support.mozilla.org/en-US/products/firefox/fix-problems/
• Explain your situation and they will try to help you recover your lost tabs.

• • Additional Tips:**

• To prevent this from happening again, consider enabling the "Open Tabs in Background" setting in Firefox. This will keep your tabs open even if you close the app.
• You can also set Firefox to automatically restore your previous session when you open the app.

• • I hope this helps you recover your lost tabs and reopen your session on your mobile device.**); is there a way im missing ?

Only thing that happened is that I restared my phone earlier?!

Just attempted to install latest Firefox update and now NEITHER program can be accessed...ERROR...Platform version 129.0.2 is not compatable with minversion>=129.0.1 maxVersion<129.0.1 NOW, I CANNOT OPEN FIREFOX AT ALL and have no access to the bookmarks, anything having to do with FIREFOX Windows 10

Please help ! TIA

Please advise if this was a bug that occurred after your 11/12 Tues. update. It appears that a patch of some sort was sent on 11/16 Saturday, but it did not help with bookmarks. I hope I don't have to use a different browser in order to save bookmarks or favorites. I also lost my Norton and Ad Muncher & had to re-set those again. I hope you have a fix for this as Firefox had a problem similar to this in late October '24. I really appreciated the stability prior to this. Thank you. P.S. What does this mean on my Firefox Settings page? Information "Your browser is being managed by your organization."
