Well if you can run interactive javascript then you're mostly there, PDF is pretty much Turing complete so you can just crosscompile a browser into it using javascript to take care of the interactive parts, though you might need to rewrite the rendering logic.
PDFs are definitely not Turing complete. [0] [0] https://www.cs.odu.edu/~zeil/cs390/latest/Public/turing-comp...
Side note: I don't know how often this happens but it's kinda cool that Firefox went straight from 87.0 to 88.0 without any sub-versions. They didn't seem to have any security/bug patches, they just got it right on the first try.

You can't use plugins like NoScript with PDFs on Firefox: https://bugzilla.mozilla.org/show_bug.cgi?id=1454760
interesting, could you embed a pdf into a webpage that has some JS which triggers automatically? Even if you have noscript?
> PDF forms now support JavaScript embedded in PDF files. Some PDF forms use JavaScript for validation and other interactive features. The amount of complexity that one can put into a PDF is both surprising and a tad frightening.
Back when I started playing D&D again, some friends stumbled across a PDF of "MPMB's character sheet" or something. Basically, it was a PDF full of scripting and options and such, that let you: * Choose which content you wanted to use (i.e. content from which sources) * Choose which rules you wanted to use (in case you wanted to use optional rules) * Choose your class, race, and background, and handle them appropriat…
Mozilla, can we have bookmarks back for new tabs in Android? Collections seemingly reinvent the wheel but limit the number of bookmarks, and force me to swipe left to view them.
And it would be great if selecting url bar would also allow me to choose one of my collections. Now I have to open a new empty tab first.

Disabled by default, right? Why would you open up such a stupid security hole?
Let me bring some news: all websites already use javascript. Loading javascript from PDFs will be just another source of javascript vulnerabilities.
Zero websites automatically get JavaScript access from me, and many other savvy web users.
If PDFs are not subject to these same controls in Firefox, then this could be a security and privacy vulnerability.
Still no update on super-high CPU usage of Twitch on Firefox, an issue that has been open for at least 4 years [1][2]. I really want to like Firefox and I want there to be viable alternatives to Chrome but when playing video back at 360p (not joking) grinds my 1.5 year old Macbook Pro to a halt on a popular website... I just can't use it. I don't know if this is a video codec issue, a CSS/JS issue that Twitch manages…
I just switched from FF to Brave. Despite the unnecessarily built-in adblocking (I prefer blocking on router level + 2nd layer via ublock) and the BAT stuff, it is a good browser. It feels so fast and snappy. I wished FF was as fast. Macbook Air M1
Yeah I moved away from FF as well after they got too political, very happy with Brave.

You're both condescending and incorrect. Bad combination! Zero websites automatically get JavaScript access from me, and many other savvy web users. If PDFs are not subject to these same controls in Firefox, then this could be a security and privacy vulnerability.
