Is there any difference in cache files for Flatpaked Firefox and the normal one?

I have been using FanFicFare application for downloading Fanfiction stories as EPub from the main fanfiction websites. It works just fine for most of them, but there are now terrible problems with the biggest of them all, https://fanfiction.net, which is behind Cloudflare and generally inaccessible to scripts.

Therefore functionality has been added to script which with appropriate flags (-o use_browser_cache=true -o use_browser_cache_only=true) and when correctly configured it can “download” HTML pages from the Firefox (or Chrome) cache instead and stitch them together into EPub same as if the pages were downloaded from the Internet.

It all works perfectly fine with Firefox as packaged by major distributions (openSUSE in my case), but it doesn't work with Firefox installed from Flatpak. Is there any difference between the storage of cache in Flatpak Firefox? Is there some kind of access protection to its caches?

This book was a bit of let-down for me. Yes, it is very nicely written, characters are well described, they have even some (slight) development to them (which is rather rare in all fanfiction stories), but it feels like painting by numbers. Elizabeth and Gardiners travel all the way to the Lake District, so there is never a meeting at Pemberley, and Lydia is ruined (for long time it seems irrecoverably, but it turns out better). Then Elizabeth meets Darcy when she hides in London with her uncle and aunt and everything proceeds as you expect. Lydia is sent to Canada to be married and saving the fame of the Bennet family, D&E have their happily ever-after, Jane finds some replacement for Bingley, who in the end (with many rounds around) marries Georgiana. Everything is very predictable and it takes extraordinary time to get there (59 chapters). If you read one of stories like this, you probably shouldn’t bother.

Pride & Prejudice meet Persuasion meet Horatio Hornblower, slightly too long and slightly failing on “Show, don’t tell” rule, but otherwise obviously professionally written thing and the tension is really high and adventure dramatic. Highly recommended.

I have heard about this story so many times, I have felt compelled to download it and read it. It is pleasantly written, I don’t have any serious complaints about it, but in the end it is just yet another indy!Harry mixed with (never explained) sudden whirlwind romance, where Harry and Daphne get from 0 (him not knowing her name) to marriage (and of course the married bed) in a week or so. If you read something like this, you've read it all, I am afraid. Interesting part is that the whole story is from Daphne’s point of view (that’s at least something different).

What in the world I have just read? It could be just one rather normal run-of-the-mill indy!Harry story with mildly evil Dumbledore where Harry will build his own base and defeats Voldemort, but the author for reasons I really cannot understand put whole story into Harry & Hermione’s (of course, it is a Harmony story, it is indy!Harry after all, isn’t it?).

Which again is nothing bad. There are really few stories in the Harry’s third year and there are many themes which could be fruitfully investigated. I would love to finally somebody utilized the best JKR sentence in whole heptalogy (“Lucky you,” said Ginny coolly.’ OotP), it is the year of Ginny’s and transition from freaked out little girl to the storm of energy she is later in the series, it is the most peaceful Harry’s year (whole year happens absolutely nothing, everything is in the end), so we could have more of non-Voldemort-happy-life-at-Hogwarts. Did author use anything of these?

No, she/he didn’t. I have absolutely no idea, why this is a thrid-year story at all, it could/should be just slightly AU fifth or sixth (even better) story as well (somehow saving Sirius is the only requirement), and even better because even with twenty+ minds in them, these are still thirteen/fourteen year old bodies going at it like rabbits. Ewww!

After reading an excellent “One Week Late” by Bethany Delleman, I hoped that this story might another (very rare) example of non-canonical pairing P&P story. I have always thought that the relationship between Colonel Fitzwilliam and Elizabeth could be very interesting to explore, and generally that a relationship with a solider (looking how well the relationship with a sailor worked in “Persuasion”) could be interesting as well. Except the story had did not much of that exploration. Since the first wedding, it was quite obvious how it will end and there were only two ways how to achieve that end, neither of one which I liked. In the end the author decided to follow both of them. Oh well.
