I have been having problems getting access to sites. I keep getting 502 Bad Gateway Certificate verify failed: unable to get local issuer certificate. What can I do? For example, I have been trying to access EFTPS to schedule payments or IRS and get same message. What should I do?

I am intermittently but repeatedly getting this message in Firefox:

> The Windows file-dialog has crashed. No file or folder could be selected.

Windows 11, Firefox 142.0.1 Most recently within www.facebook.com Edit Album

Is this a known problem? And does it have a solution?

Is there a way to change to size of the font on the tabs? It's very small. I've tried through settings, changing the letter size but it doesn't change the type on the tabs. Help!

Suddenly, I can no longer log in to iCloud on my MacBook Air from Firefox: I get the login alert and the code to validate the connection, but the window to enter the verification code doesn't appear. It says "enter" the code, but I don't get the window to do so!

I'm on Big Sur 11.7.10, it worked without a hitch for years. This laptop is one of my trusted devices. Is a recent update preventing the connection?

I looked at similar questions, and answers from 2020 said to add the 6-digit code after my password, but that solution doesn't work.

It seems the problem is with Firefox; it works on Safari. Any solution for Firefox?

Thanks

After doing the last up date of Fox Fire on or about Aug 27, have not been able to load Fox Fire with all of the previous files, start menu bookmarks/history. Tried restarting as suggested but no luck. Benn dealing with this for several days. Unable to get to Outlook to get email, etc,. Is going to be difficult to email me as not able to get into my email. Did several restarts as explained in Fox fire. I might be able to get into email using my phone.

All the help articles do not really explain how to restore Fox Fire to a previous point. At least in all the articles I read.

I have an Occasional Issue where Youtube Stutters, or lags. A good example is When I Press Pause the video will respond 5 Seconds Later. Or When I grab my mouse it will dissapear when I reach the video box. I do have You tube premium, and I do have U- Blcok origin and Malware bytes. But U- block and Bytes are disbaled on any youtube page, And I pay for Youtube Premium as well.

I use Bitdefender as antivirus program. When I start up Firefox the antivirus program blocks the start up because it says Firefox is trying to access a program (sync.contextualadv.com) which does not have same authentification as the target. It gives me choice to accept this as an exception if I want. I don't understand the details but I don't want to allow this to proceed until I'm sure it is safe. I'm on an HP computer running Windows 11. I use firefox on another laptop running Windows 10 and have not had this problem.

The "History" tab does not show recent history. I cannot recover recent internet locations because the history does not include them. It shows the same older history over and over. When I request "all history" the list ends in August. It is not reassuring that the history shown is multiple sites of my online use, of Vanguard the investment company.

I have searched for an answer to my question, but I can't find one. I have checked the settings in about:config to make sure PDF editing is enabled, and made sure pdfjs.enableHighlightEditor is set to true, and pdfjs.annotationEditorMode is set to 0, but the edit options, like adding a signature, drawing, adding images and adding text are all still grayed out. I'm trying to sign a form, and it's annoying to have to print it out to sign it and then scan and upload it again. I even changed the PDF editing permission to "true" in about:config, thinking that might fix it, but it didn't change anything. I don't understand why nothing is working.

I've lost everything in bookmarks. The toolbar. The general bookmarks. Everything. Could this be because I tried to download Claude on my new mac mini. Help please. We only use firefox. All the time!

I just reorganized all of my bookmark folders, as well as bookmark locations inside my folders a few days ago. 5 minutes ago I updated my Firefox desktop browser and now my bookmarks are all messed up & my newer folders are missing. Why is this happening & how do I stop it?

These icons appeared recently in my Firefox browser I can't remove them. The only recent changes included uninstalling SuperAntiSpyware after finding that Microsoft PC Manager is a better option, which has performed excellently without issues.

Additionally, a free VPN (Proton) was briefly used from the Firefox browser without installation, but after finding it complicated to set up, it was deleted. A few hours later, I noticed the two icons as the windows were misbehaving and they are causing a slowdown in the PC's performance. They do not seem to be add-ons or extensions.

How do I remove the icons and return to the previous performance?

I've noticed that Youtube videos on Firefox are far more washed out when compared to Google Chrome. HDR is enabled on my Monitor and in Windows 11; however, the issue is present for standard SDR videos as well. Any idea what is going on here?

Suddenly I cannot log into icloud from your browser. I can log in using other devices and other browsers. Fire Fox gives me an error message "Failed to verify your identity. Try again"
