firefox – Who do my other profile’s bookmark icons, extensions data, sessions … disappear?

I have my work profile accessible via about:profiles on my personal computer. Only the bookmarks are sync’d with Firefox Sync. After some days without accessing the profile, I open it again and:

  • all the bookmark’s icons disappeared
  • the extensions’ data disappeared, I need to reconfigure all the extensions
  • the firefox’s theme disappeared
  • all my sessions (gmail, gitlab…) are closed, as if I never connected to them before

Why? That’s excessively annoying. I just wanna give up Firefox for my work profile and move to Chrome.

Can Chrome Extensions Send Data to Remote Servers?

Suppose an extension has a scary list of permissions like that below (“Site access: On all sites”):

enter image description here

Does this also give the extension permission to send my data to the author’s servers via XHR?

I’ve read the documentation here but lack some background knowledge, so I am not sure in my interpretation:

Cross-Origin XMLHttpRequest

After reading this, it seemed like the extension isn’t allowed to send my data somewhere unless it has lines like the below in the manifest – is this correct?

"permissions": (

spfx extensions – Random bug with settings menu not loading on SP Online

I’m getting a random bug when my Settings menu (Gear icon in the top right corner) does not appear sometimes on my SP Online site. I found that when it happens I have an error in my console (see below).

When I refresh the page it is all good, if I refresh 10 times, I’m getting this problem 2-3 times. Looks like some race condition is involved. I’ve traced the error and it looks like a bug in SP JavaScript code.
It all looks like:

enter image description here

Here are all details about the error:

The console error:
This error I see in console

Here is the piece of code where the bug sits:
enter image description here

So line return e.Id === n.newWorkloadSettingLink.Id fails because e sometimes null. I traced the source of e and it looks like it an iteration from _spPageContextInfo.MenuData.SettingsData array + merged with something else (+5 more elements) where one element is null in my case (item with index 3).

enter image description here

If I’m fast enough (can include script which runs on a page before the error call) and run the following block of code on Init in my Application Customizer extension, error disappears:

    const links = _spPageContextInfo.MenuData.SettingsData;
    for (let i=0; i < links.length; i++) {
      if (!links(i)) {
        links.splice(i, 1); // Removing item if it has no value

But this is kind of hack, and obviously, I need some help to understand how to resolve this issue for good. Does anyone have any idea why do I have one element in the array set to null or why Microsoft has this bug?

PS.: I play with SP on my own non-commertial research project and don’t have any MS support subscription. Anyway I don’t believe they will fix this bug for me in shot time as they are a bit slow sometimes. My last hope that someone from the community already saw/solved something like this 🙂
Thanks everyone in advance!

magento2 – PWA Studio with custom extensions

First of all, sorry if the answer is obvious. I read the Devdocs, PWA-Studio Docs and some Tutorials, but somehow couldn’t wrap my head around this.

Does using a PWA with Magento2, for example Magento’s PWA-Studio, require me to add a GraphQL API to every module I use for this shop? Or can Magento somehow “skip” PWA-rendering when no GraphQL is in place?
For example, I mean modules we created ourselves, modules we bought from 3rd parties, as well as payment methods (where the PWA docs state that it’s currently only compatible with Braintree, which is not much imho).

Also, I’d be glad to get any tutorials on how to make a custom module PWA-compatible.

ct.category theory – Characterize right kan extensions among copresheaf-pra’s


Let $P$ and $Q$ be categories, and suppose $P$ has a terminal object $ast_p$. A parametric right adjoint, or pra, $F$ from $P$ to $Q$ is a functor $F:Pto Q$ such that the functor
$$F,/,{ast_p}: P,/,{ast_p}to Q,/,F(ast_p)$$
induced by slicing over $*_p$ is a right adjoint. In particular, since right adjoints preserve terminal objects, note that every right adjoint $Pto Q$ is a pra.

Suppose that $C$ and $D$ are categories, and let $P:=C{-}mathsf{Set}$ and $Q:=D{-}mathsf{Set}$ be the associated copresheaf categories. A functor $fcolon Cto D$ induces a pullback functor $Delta_fcolon D{-}mathsf{Set}to C{-}mathsf{Set}$, which has both a left adjoint $Sigma_f$ and right adjoint

Pi_fcolon C{-}mathsf{Set}longrightarrow D{-}mathsf{Set}.

In particular, $Pi_f:Pto Q$ is a parametric right adjoint.

Remark: A functor $C{-}mathsf{Set}longrightarrow D{-}mathsf{Set}$ is a pra iff it is isomorphic to one of the form $Delta_e,overset{circ}{,},Pi_f,overset{circ}{,},Sigma_g$, where

and $g$ satisfies the relatively strong constraint of being a discrete opfibration. This fact is due to Mark Weber.

Definition: Let $mathsf{pra}$ denote the category whose objects are categories $text{Ob}(mathsf{pra})=text{Ob}(mathsf{Cat})$ and for which a morphism $Cto D$ is a pra between their copresheaf categories
mathsf{pra}(C,D):={Fcolon C{-}mathsf{Set}longrightarrow D{-}mathsf{Set};mid;Ftext{ is a pra}}.

We refer to $mathsf{pra}$ as the category of categories and copresheaf-pras. It is in fact a bicategory whose 2-morphisms are natural transformations.

Question: Inside the bicategory $mathsf{pra}$ of categories and copresheaf-pras, can one characterize those morphisms that are right Kan extensions $Pi_f$ along some functor $fcolon Cto D$?

google chrome extensions – Hide “What’s Happening” and “Who To Follow” on Twitter

Because the divs have random hash classes I can’t figure out how to hide them or what to hide them with. These sections take up an insane amount of space and the content is terrible, would love to hide them.

I tried div[aria-label="Timeline: Trending now"] {display:none;} with Stylish but either the selector or chrome extension didn’t work.

sharepoint online – Can we remove file extensions from default Name column of document library?

We have document library with .pdf, .docs, .pptx, .url and .jpg type files and file viewer web parts to preview those files. But customer want to remove file Extensions from the Name column and want to keep the link to document with edit menu option in Name column.

So, how can we remove the file extension (.pdf, .pptx, .doc) from the Name column?
