Dont open *.mht format


(gegemon2012) #1

Hello!
I recently switched to quantum and the first trouble I encountered is problems with opening files in mht format … When I try to open files created with addon UnMHT via quantum, the “save as” dialog appears and prompts to save the file in mht format which then opens with the dialogue “save as” and so on ad infinitum. However, these files are opened without any problems by Internet Explorer. For a long time these children’s sores have been cured in many browsers. Is it really so difficult to add native support for mht, maff and similar files?

I think the demand for those formats is just to low. Many modern pages either work offline out of the box, can’t be saved at all or can be saved as PDF of screenshot.

As for the UnMHT extension (whiteout knowing it) I think you have to use some UI element of the extension to open the file and cant just “open it with Firefox”. AFAIK WebExtensions can’t install file format handlers, i.e. Firefox doesn’t know to forward the file to the extension.

Hmm … Then why such files are opened by Google chrome and Internet explorer?
I now have to set myself google chrome, save the file in pdf format to open it in firefox … Not very convenient …

Time to switch to a different browser. Mozilla has decided to prioritize speed over functionality and will not support extensions like this in the future. The Waterfox fork continues to work with “legacy” extensions.

Ironic that they designed MAFF as a future-proof format and are now the ones abandoning it.

Thanks a lot, endolith! I’ll try it. I think it can solve my problem.
I’m sarcastic in my turn. Once again I am convinced that it is necessary to establish a separate computer for the good old trusted programs.

Mozilla friends,
Include MHT save in new version of Firefox, please

Isn’t it something you can tune in Firefox Preferences > General > Files and Applications ?
