Firefox Support Forum

Hi, I get the below error message when trying to login to visma.net (for work).

json.parse unexpected character at line 1 column 1 of the JSON data

On this note I have a previous error, loggin in to this site that was fixed by a support member (• accessibility.blockautorefresh = false), but I have the above hurdle left. I can get past it by clicking backspace but thought there might be a better solution - maybe some other setting I can adjust similar to the first fix I got help with.

The web address for this error message shows as: https://api.home.visma.com/home/rest/sso/login

hello. I have a reproducable issue with Firefox. If I use the touch keyboard on Firefox and then exit Firefox without without closing the touch keyboard, when I next start Firefox it only opens with a half view. if I close the touch keyboard first and then exit Firefox it opens as normal in a full screen view. it has nothing to do with either an extension or a theme. is there any way of ensuring that FF opens in full screen view if I forget to close the touch keyboard before exiting the browser? thanks in advance. PS: device is a Surface Pro 7 running Windows 11.

thank you

At some point, I've noticed that certain behaviours expected to occur when pressing the Escape key no longer did. Those behaviours mainly involved triggering some Javascript, including functionality in keyboard-related extensions, such as Tridactyl. Browser-level functionality on the other hand, such as pressing Shift-Escape to open `about:processes`, or pressing Escape to close Search Suggestions when the URL input bar, continue to work as before.

Upon investigation, I found it is specifically the javascript Keydown event that isn't being registered, while the subsequent Keyup event still is. I used https://w3c.github.io/uievents/tools/key-event-viewer.html to test this.

I also found that starting Firefox in Troubleshoot Mode (Safe mode) doesn't resolve the issue. On the other hand, creating a new profile does.

I've looked at the modified settings in `about:config`; there's a lot, but nothing stands out as being related to keyboard input or javascript.

Can someone please help me find what is causing this?

I Closed the browser and forgot that I had a private one open too. When I went to open the main Firefox window up, my previous session was wiped! I already tried the right clicking plus sign method to no avail. It just brings up the one I had after searching how to bring back the session and then accidentally closed the browser after. Any tips on how to get it back? Why does this happen just because you have a private window open??? Change that ASAP!

Lastpass extension/icon isn’t showing up in Firefox IOS. I’ve installed the latest versions of both. Firefox menu or settings doesn’t offer a plugins or extension link anymore. It seems Firefox has lost functionality in this regard. Please advise on how I can get the Lastpass extension working in the Firefox browser again.

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have macOS and there are no Extensions for the iOS version.

The "Digital Advisor" page on vanguards website (after logging in) seems to default to a white background even when in dark mode, resulting in the page being unreadable due to the light gray/off-white text. It seems to only be on the digital advisor page, though. When viewing other accounts or sections, dark mode seems to work correctly.

HTTP/3 doesn't work regardless of my config:

network.http.http3.enable = true network.dns.httpssvc.http3_fast_fallback_timeout = 0 network.http.http3.priority = true

and https://cloudflare-quic.com/ and console still show I'm using HTTP/2. Tried on Firefox nightly and chromium (chromium works fine but firefox doesn't.)

Everything was working fine on Firefox up until a couple weeks ago when my searches started lagging.

What happens is - if I type a search into the main URL/search bar on the browser, it loads just fine. But if I type a 2nd search into a website search bar, such as on google.com, there is about a 12 second delay between me hitting enter and the page actually starting to load. The page freezes during this time and is unable to be interacted with. This issue does not happen in any other browsers outside of Firefox.

Things I've tried so far: Troubleshoot mode/safe mode, clearing cookies and cache, uninstalling and re-installing Firefox

Nothing has helped... wondering if this was caused by an update?

A few days ago links in messages stopped working in Outlook (Microsoft 365) on my Windows 10 Pro 64-bit PC.

Good ol' Microsoft support reset Firefox on the PC and I lost all bookmarks, history and personalized settings. Tried to copy data from Old Firefox Data file into profile on reset Firefox. Didn't work. Uninstalled and reinstalled Firefox and tried to copy data from old profile to new profile. Nada.

Only option now is to try to sync Firefox on my Mac to new install on PC. I'll still lose some bookmarks and history but it will be better than what I have now. I have a Firefox account on both devices but when I log in to Firefox on the Mac I cannot find anything pertaining to sync.

Problem one: how do I navigate to sync in Firefox for Mac. Problem two: when I bought the Mac 6 years ago I tried to sync Firefox on my PC to the new Mac. For some reason Firefox synced the empty new profile on the Mac to the old PC. I lost all bookmarks and history accumulated on the old PC! I do not want to go through that again.

I have never found anything on Mozilla that clearly explains how to control which way the sync works. Must be certain that I'm copying all the bookmarks, history, tabs etc, from the old device to the new on and not vice versa.

Please HELP -- I can no longer use Thunderbird or Firefox to access my emails at the University of Vermon (UVM). For over about 2 months after the Univ. of Vermont went to a new email system, I can no longer use Thunderbird or Firefox to get my emails. I get an error message when I enter my NetID and password at

https://adfs.uvm.edu/adfs/ls/        or   https://webauth.uvm.edu/webauth/login?RT=ZQy0vGaH7hXE%20BIXYqeBrf8AW817EA2ZEgHD5NywxXEKicTPOPs4jvfqMM1T9WiTY2sJpxG3mUbgwZ%20oW%20wliuVFGhQ9vFzD12bdJTM4FXUcyuQi%2Fo6%2F7zhAZ2ez%20uYFe0ds5tUDcQVhf%20jzr0i1MSDJlBZ%2Fqp6YXfHB3zHgNlGsV3eb0QbClx9lt6AtFahFGLLykYMswanRENJNTkXaRe%2FHypzNXIcppX22Ota7hGSkkVx7g2ChYFxgPaK2W1xDgpAMNS8O1F6HfjOao96aRrWOo4Ltqb0jfSHYpYRjantewrxjZUHG9yiLS1yI6C3YR06tb84wb6%2Fs4lUrDAJadCfJz3GJP8qkOJyrSmjI0%20%20WMo8U;ST=ZQyp228WbdkSw1QKFNvUgJvqzpLVg0x5cQFiBGwk3jd9QLdWxEo7Wg90eK09yvoz1npFIMkViO0k3J3d8%20prFPvXmkpA99rhjvwO9qDqHU8ZvduICJM8IjgoqGCTfAUUjg3k280qveVCzlkbyJtJ4rga3RFnod9IrEbgHy2dgeBcXuop;test_cookie=1

Hi! I have two Firefox accounts, one for work and one for personal use. I often have them running on the same computer at once (this does cause them to crash occasionally, but not often enough to be a problem). However, today I tried to log into a website where I regularly do freelance work and received this error code: "Error code: SSL_ERROR_PROTOCOL_VERSION_ALERT"

I would assume something was wrong with the website itself, however when I went to that same site on my other account, it loaded just fine. I've restarted my computer, restarted firefox, deleted cookies and caches and browser history, but still get the same message on my work account. Any idea how to fix this?

Thanks!

I don't know when it started (quite awhile), but when I go to some websites even in FF safe mode, I wait a long time but get nothing displayed and it stops spinning/waiting (the circle arrow upper left stops). Occasionally when I reload, it comes up but usually it doesn't. Other websites it works fine.

In fact, if I browse to some websites, sit and wait awhile, then go to chrome or edge, type in the same website, the page displays even while FF is sitting there waiting.

ebay.com seems to work great, but for instance this morning, this one doesn't: https://www.crowdpac.com/news/741938 but sometimes this works: https://www.crowdpac.com then try it again (refresh) and it never responds.

And in fact, I'm using Edge to submit this question because when I browsed to https://support.mozilla.org/en-US/questions/new/desktop#search in Firefox/Safe and clicked on the Sign-In/Up button, nothing happened. With Edge it worked fine and I'm able to type this in.

I need to install Firefox on a new laptop under an existing account, but a new account was already created on the new device. All it will let me do is reinstall under the newly created account.

Dear Sir/Madam:

I am using Firefox Browser 102.15.1esr (64-bit) on a MacBook Pro Ventura 13.5.2.

I have been using the www.dictionary.com website for a long time, but recently when I attempt to go there, I keep getting the error message as follows:

Unexpected Application Error! FM.findLast is not a function

WM@https://www.dictionary.com/client.e12a2de6.js:36:305976 $o@https://www.dictionary.com/client.e12a2de6.js:1:26519 ka@https://www.dictionary.com/vendor.60d89d9a.js:1:864941 xu@https://www.dictionary.com/vendor.60d89d9a.js:1:921923 bc@https://www.dictionary.com/vendor.60d89d9a.js:1:910907 yc@https://www.dictionary.com/vendor.60d89d9a.js:1:910835 vc@https://www.dictionary.com/vendor.60d89d9a.js:1:910696 ic@https://www.dictionary.com/vendor.60d89d9a.js:1:907503 oc@https://www.dictionary.com/vendor.60d89d9a.js:1:906055 E@https://www.dictionary.com/vendor.60d89d9a.js:1:996565 P@https://www.dictionary.com/vendor.60d89d9a.js:1:997096

I tried clearing caches under Privacy & Security, but the problem persists.

(Meanwhile, I can visit www.dictionary.com on Safari and Google Chrome.)

Could you please let me know what is going on?

Thank you,

Roland

I've been having an issue for a while now where the cloudflare challenges that ask you to click the check mark to "verify your connection is secure" would just endlessly ask me to click the button and never continue. Sometimes it would say to unblock access to challenges.cloudflare.com.

But if I a launch an incognito window I can visit website with the challenge and it won't even ask! I've added all my extensions to run in incognito mode and everything still works, I can visit the websites in incognito just fine. So the one changing variable is incognito vs non-incognito.

I can have two windows open, one incognito and one not, and browse to the same website and the non-incog window will fail but the incog will just go to the site.

I thought incognito was supposed to only affect the session storage? Does it silently change other things to the running environment of the browser (about:config options, slightly different extension configs)?

Anyone know why this small change would suddenly allow cloudflare challenges to work?

Firefox 117.0.1 (64 bit) Build 20230912013654 Windows 10 Home - Version 22H2 OS build 19045.3448 The link to download my Sears credit card statement in pdf form has disappeared when accessing the website (https://citiretailservices.citibankonline.com) with Firefox. It still appears and works normally when the website is accessed with Chrome. I have the uBlock Origin extension installed on Firefox, but it is disabled on the Sears website. Screencaps attached.

Embedded videos play on Safari but not Firefox. When I looked at the previous questions about this they were addressed in June 2012. Apparently it is happening again, at least in my case. Maybe it happened with the last upgrade, I don't know, but I never had this problem before. Would appreciate any input. I haven't changed any of my settings. Thanks.
