Firefox Support Forum

I was looking for an item that would be a couple of years back in my history, only to discover that my history now only goes back a year and 3 months… Exactly, as of today, I don't know if that's meaningful. Does anyone have any idea what might've happened, and how I can restore the rest of my history? Thank you!

I'm on a Mac using Mojave, with Firefox version 115.8.

As you can see in the attached image the highlight is coming out grey instead of blue, which is what is showing when I select 'save screenshot'. It used to be this error happened maybe one in 20 times and it was annoying because I am making these screenshots for use in youtube videos and it becomes unreadable, but now it is every single screenshot even after doing it dozens of times and with different pages.

I often run into issues with PDFs in Firefox Linux. They either appear totally blank (typically after suspend/restore), or they appear with the desktop background showing through (as in the attached screenshot).

Hard refreshing the page doesn't change anything, opening a new tab and opening the PDF again doesn't change anything, opening a new window and loading the PDF doesn't change anything.

The screenshot is with this PDF: https://www.sgsw.ch/home/strom/_jcr_content/Par/sgsw_accordion_list_1838160259/AccordionListPar/sgsw_accordion_12353/AccordionPar/sgsw_downloadlist/DownloadListPar/sgsw_download_1049323524.ocFile/2023-08-31%20Mitteilung%20Elcom%20Erh%C3%B6hung%20Elektrizit%C3%A4tspreise%20f%C3%BCr%20das%20Jahr%202024.pdf

It renders correctly in Chromium.

Firefox 126.0 using the recommended performance settings on Mint 21.3, nvidia quadro p620 using the official nvidia drivers v535.171.04-0ubuntu0.22.04.1

Whenever I m visiting to my website I m facing an issue like getting a horizontal black line near the scroll bar, it is coming up when I make my browser window responsive to the resolution of 1920 X 1080 and when the zoom level is decreased to 90%, 80% & 67%.

This issue I m not facing in other browsers like chrome, edge.

Below is the screen shot attached,

When I see a highlight reference to browser settings: Java Script enabled; otherwise Firefox wont operate properly. How to know Java Script is not enabled (vice-versa). I'm not sure that I have seen a switch Or toggle to know JS is On/Off

I was scrolling trying to make cards for Father's Day and there was a pornographic image where there should have been a fairytale castle coloring page. How do I make sure this does not happen again?

Hi,

more Details concerning the problem you can see here ! It should be great if you could help us with some diagnostics, for example why the problem only appears with FF on Linux, not with FF on WIN.

STR:

1. Launch Linux FF
2. Visit this page "Potential issue with plugin PITM" (Preview here
3. Because you will need an Account for visiting account please follow "Konto eröffnen" (Create Account) instructions).
4. After my approval for the account please visit again "Potential issue with plugin PITM"
5. Click "1.png" Below heading "Attachments", that should work without problems.
6. Close image view
7. Move Mouse pointer to image below heading "My test with a screenshot" – should become magnifier
8. Now Click that image

  » Expected (and so it does with WIN): Big image opens in new TAB
  » Actual:  New TAB opens, but without image view.

What are your results? FF Linux Problem or something else?

Few days ago I started to have issues with Zoom Meeting recordings playback. When I open the video it clocks but doesn't start playing. I never had this issue before. Zoom support cannot replicate this issue. They say everything works for them.

I cleared cache and history, restarted my computer but that didn't do anything for me - video still clocks. Playback works fine on Chrome. Somehow playback on Firefox stopped working for me. I am using the latest version.

Please help

Firefox.exe -silent and Firefox.exe -silent -p default work, but Firefox.exe -silent -p MyProfile Not

Do it is possible to preload Firefox with a custom profile with extensions, without stay visible, to speed firefox istance open?

-os-autostart What exactly does it do?

For some reason I notice that some of our image files, viewed after opening an online pdf document with images within, shows random white horizontal lines. This is not shown using edge or chrome. you can go here to view https://mcclone.net/wp-content/uploads/2024/05/Connects-Issue-12.pdf.

Any help would be appreciated.

Thanks Chris

Running Win 11 Pro with the Firefox - 64 bit - All updated per June 9th.

ISSUE: Website tells me I have an 'add blocker' or the product 'addblocker' installed. I don't. However I get blocked even viewing my own website: fleksjobbernetvaerket.dk .... and others as well.... It's full of Google ads.

SOLUTION: I searched for how to solve this, but none of it is working, not even re-setting or re-installing Firefox, emptying cache, files and folders. I kinda gave up on this.

Hope you can help.

thanks Knud
