FireShot for PM in Linux Mint?

Post by f-117 » 2025-12-11, 01:50

I am trying to install FireShot Pro on my PM in Linux mint.

But I saw on the PM Addons download page it says "Pale Moon 27.0.0 to 35.* " Below this it says " * OS Windows only"
Does this mean that FSP is only available for Windows? Not Linux?

What do you think it means then?

The version * stands for incremental updates between 35 and 36. In fact, most addons even saying they're only supporting 34 or below may just work well on 35 and above. Some use x to indicate missing numbers/letters, but * is also acceptable. The clash is unfortunate but, after a re-read, easily separated from each-other.

As to FSP only being for windows, it's not. It just that some things don't work. Namely those starred in the addon description text (not version text. Some also use sup-numbers like wikipedia for this12):
Annotated *
Uploaded *
E-Mailed *

* OS Windows only
There's also https://addons.palemoon.org/addon/simple-screenshot/ you can use.

Off-topic:
When it comes to Linux Mint, based on Ubuntu, I wish people would include what desktop environment they are using in Mint such as Cinnamon, Mate or Xfce. I say this because some applications which are installed by default in Cinnamon are not installed by default in Xfce. An example is Night Light which works in Pale Moon and is found in Cinnamon so an extension is not needed. But Night Light is not offered in Xfce
Getting back on topic, if the OP wants to use the substitute application named Screenshot, it is in all three desktop environments in Linux Mint. Screenshot is a replacement for Fireshot.

It is listed in/under the heading Accesories in the Mint menu. I used Screenshot in linux Pale Moon when I was using Mint in Xfce so an extension is "not" needed. I now use Screenshot in both linux distros MX Linux and Debian.

I "guess" Screenshot is installed by default in LMDE (Linux Mint Debian Edition), but I am not sure because I never used LMDE.

Fireshot Pro uses a helper executable to perform its more advanced tasks like on the fly editing. That is for Windows only iirc.

Fireshot is meant to screencap whole webpages,not the desktop , which is why it is supplied as a browser extension. Otherwise each DE has its own supplied screenshot taking as well as editing tool.I use KDE's built in Spectacle.

Off-topic:
It is also a tool in devtools (ctrl-shift-i/other ways of getting devtools -> toolbox settings -> take screenshot of whole page checkbox to get the button in devtool, that's how I found it), which can work for quick'n'dirty, extensionless screenshots too.

Yes. as mentioned FSP saves/print's the entire (Multi-page) website with page breaks for each page, which is what I need.

Screenshots will save/print the entire (Multi-page) website on one single printed page (Fits all the pages on one page).

I need the add-on to give the page breaks for the entire (Multi-page) web site.

This is why I need FireShot. It just works great on Windows PM. But I am having trouble on my LM PM for some reason.

I contacted FSP's support service and am waiting for a reply...

I just tried installing FSP in Linux Mint PM again.
(I do have a valid registration key)

I keep getting the following message...

___________________________________________________________________________________________________
— Error: couldn't open library sss64.dll: error 126

Description: FireShot could not run the library "sss64.dll". The file can be damaged, blocked, or deleted.

Solution:

Check the logs in your anti-virus program. If the file "sss64.dll" is blacklisted, whitelist it.
Check, if the file "sss64.dll" exist (you should see the full path to this file in the error message).
If the file does not exist in this folder, reinstall FireShot.

____________________________________________________________________________________________________

The file does exist here:
Moonchild Productions\Pale Moon\Profiles\ck189j3s.default\extensions\{0b457cAA-602d-484a-8fe7-c1d894a011ba}\library

I checked the file and it seem OK. It is not blocked by AV (Don't have one on LM)

That' where I'm at with FSP on LM.

Scott

P.S.

My mistake... I think this topic belongs in the Add-Ons section...?

A .dll is a Windows binary, which is very unlkely to run on Linux.

This is something you may not want to see, but Reality does bite at times and this is one of those times where Reality bites. If you do not get want you want from FSP's support service and they will not write a linux version, then you are relegated to three outcomes.

The first outcome is, there are some programs which are strictly Windows only and will not have a linux version. And as of this moment in time, FSP is one of them.

The second outcome is, you find a suitable replacement, not an exact replacement for FSP, that you can use in Linux Mint.

The third outcome is, if you have to have FSP and you will not settle for anything less than FSP, then you will have to give up using Linux Mint and return to Windows to use FSP.

This is the long and short of it.

A fourth potential option and compromise would be to use a compat layer like WINE or Proton to run the Windows version of Pale Moon and FSP in Linux.

I am not a fan of WINE when it comes to running a Windows only program, like FSP, in Linux. This is "hit or miss" since WINE doesn't work that well in Linux (in my opinion).

But there might still be another fourth option which I just thought of. How about putting an installation of Windows 10 into a folder in a Linux distro, such as Mint, ala "a virtual machine" where FSP should work?

Mozilla's original extension system is designed to allow native libraries for specific OSes - this also means an extension developer can choose to support only a few. The extension manifest can be set to restrict installation to specific targetPlatforms and even to versions of Windows/Mac OS (though no idea if it can identify anything newer than XP correctly) and whether they are 32 or 64 bit. It's likely the author doesn't have additional hardware let alone the inclination to support Linux or Mac since that would require writing and compiling binaries separately for those platforms and adding to the maintenance overhead.

For now you're stuck with Simple Screenshot with its limitations, else look for an equivalent extension for ChromeZilla browsers and use one of them when you need to capture a webpage.

Thanks everyone for the advice. I appreciate it!

I'm going to stick with using my duel-boot Win10/Linux Mint setup. It's probably my best option at the moment.

Still have not heard back from FireShot support. I have a feeling they will probably say "We don't support Linux"...

Do I understand correctly that the issue is with Pro version specifically? Basic screenshooting seems to work on Linux Pale Moon with non-Pro version. No multi-page screenshots from what I can tell though.
